what is process control?

Process control is a statistics and engineering discipline that deals with architectures, mechanisms, and algorithms for controlling the output of a specific process. \n\nFor example, heating up the temperature in a room is a process that has the specific, desired outcome to reach and maintain a defined temperature (e.g. 20°C), kept constant over time. Here, the temperature is the controlled variable. At the same time, it is the input variable since it is measured by a thermometer and used to decide whether to heat or not to heat. The desired temperature (20°C) is the setpoint. The state of the heater (e.g. the setting of the valve allowing hot water to flow through it) is called the manipulated variable since it is subject to control actions.\n\nA commonly used control device called a ‘’’programmable logic controller’’, or a PLC, is used to read a set of digital and analog inputs, apply a set of logic statements, and generate a set of analog and digital outputs. Using the example in the previous paragraph, the room temperature would be an input to the PLC. The logical statements would compare the setpoint to the input temperature and determine whether more or less heating was necessary to keep the temperature constant. A PLC output would then either open or close the hot water valve, an incremental amount, depending on whether more or less hot water was needed. Larger more complex systems can be controlled by a Distributed Control System (DCS) or SCADA system.\n\nIn practice, process control systems can be characterized as one or more of the following forms:\n\nDiscrete – Found in many manufacturing, motion and packaging applications. Robotic assembly, such as that found in automotive production, can be characterized as discrete process control. Most discrete manufacturing involves the production of discrete pieces of product, such as metal stamping. \n\nBatch – Some applications require that specific quantities of raw materials be combined in specific ways for particular durations to produce an intermediate or end result. One example is the production of adhesives and glues, which normally require the mixing of raw materials in a heated vessel for a period of time to form a quantity of end product. Other important examples are the production of food, beverages and medicine. Batch processes are generally used to produce a relatively low to intermediate quantity of product per year(a few pounds to millions of pounds). \n\nContinuous – Often, a physical system is represented though variables that are smooth and uninterrupted in time. The control of the water temperature in a heating jacket, for example, is an example of continuous process control. Some important continuous processes are the production of fuels, chemicals and plastics. Continuous processes, in manufacturing, are used to produce very large quantities of product per year(millions to billions of pounds). \nApplications having elements of discrete, batch and continuous process control are often called hybrid applications.\n\n\nExamples\nA thermostat is a simple example for a closed control loop: It constantly measures the current temperature and controls the heater's valve setting to increase or decrease the room temperature according the user-defined setting. A simple method switches the heater either completely on, or completely off, and an overshoot and undershoot of the controlled temperature must be expected. A more expensive method varies the amount of heat provided by the heater depending on the difference between the required temperature (the "setpoint") and the actual temperature. This minimizes over/undershoot.\n\nAn anti-lock braking system (ABS) is a more complex example.

This is the new term for industrial engineer.\n\nWork in this field (which is what I do!) is filled with statistics, process control, and quality adherance. You could spend days calculating BOMs, routings, optimizing capacity and schedules, or inventory. Many process engineers like puzzles and like to continue to work at the same problem, trying to improve on specific value measures over time- things like machine down time, usage rates and batch efficiencies, days on hand of inventory, etc.\n\nI find the field to be a more people oriented form of engineering, more interactive and creative. I migrated to it from the lab-techy engineering areas of chemical and mechanical. I enjoy it!

Basic process control concepts. (Process Control).(Brief Article)\n \n\nThe basic functions of statistical process control (SPC) include the use of statistical tools to characterize processes, determine their inherent variability, monitor whether or not the processes are in control, and ultimately optimize processes and their control. Successfully implementing SPC requires an understanding of several fundamental concepts: \n\n* Variability is inherent in manufacturing. We must analyze and try to minimize this variability. \n\n* Ceramic manufacturing is very complex, with many poorly understood process interactions. We must begin to better understand these interactions. \n\n* Effective ceramic process control requires personnel versed in both SPC and ceramic technology, a weakness for many manufacturing organizations. \n\n* Making measurements to characterize a process will add measurement variability on top of true process variability. \n\n\nhttp://www.qcinspect.com/video/spcbasic.htm\n\nhttp://www.xlp.com/basic-spc-video-training

In Control System theory analysis of processes can be made as a function of input to the system being controlled and the output which is the out come of the input.\n\nSo the in phsycology we can examine a person capacity by observing a persons response to a stimulus. The Input is the stimulus and the person is the system and the response is the output.\nThis can be represented  by a diagram.\nThe system is drawn as a block with represents what is in the sytem. So if we know what the out put and the out put is we can determine what makes the system tick.\n\nThis is done by taking the ratio of the input to out put.This ratio is called transfer function. This transfer function is usually expressed as differential equations. These equations can be solved to determine the response of the system.\nBlock diagrams can be used as a topographical tool of analysis.

The electronic circuitry that controls and manages the operation of floppy or hard disks installed in the computer.\nn computer science, a special purpose chip and associated circuitry that directs and controls reading from and writing to a computer's disk drive. Transferring information to and from a disk drive is a complex operation, and a disk controller handles such tasks as positioning the read/write head, mediating between the drive and the microprocessor, and controlling the transfer of information to and from memory. Disk controllers are used with both floppy disk drives and hard disks. ...\nA hardware circuit which translates instructions about disk access from the operating system to the physical disk. This provides a layer of abstraction that means that an operating system does not need to know how to talk to the many different types of disks, but only needs to know about the (comparatively low) number of types of disk controller. Common disk controller types are IDE and SCSI.

business process\nAn action taken in the course of conducting business. Whether manual or automated, all processes require input and generate output. Depending on the level of viewing and modeling, a process can be a single task or a complicated procedure such as building a product.\n\nIn a business information system, a business process is the application of a business transaction against a database (transaction vs. master). See business process modeling and information system.

I'm a Materials Engineer (close to a Chemical Engineer) and am not familiar with a slogan for chemical engineering.  Chemical Engineers do many things, but many times are concerned with chemical processes, that is, desiging how the chemicals react and where the chemicals flow.  So a similar name might be Chemical Process Engineers, although process engineers are a little more concerned with controlling large scale production, while Chemical Engineers are more concerned with developing a functioning chemical process.  Does this help?

The two terms are often used interchangeably, but the difference is, in simple terms:\n\nQuality control is the process of measuring the quality of the product... checking it to make sure its up to standards,\nQuailty assurance is developing and putting in place, methods of keeping the level of quality up...  designing the manufacturing process to maintain standards, for example.\n\nSo, assurance is preventative...  control is measurement

In a multi programming environment a processor may handle no. of programs at a time. Each program may have more than one modules running simultaniosly (for eg. u are opening two files in different windows of a notepad) then there will have two process for notepad.exe. Processor handles all the processes in a system in time sharing basis. Process is a program module submitted to the processor for execution.\n\nStepping is the revision/version number of a processor. (for eg. intel p4 2Ghz processor will have many versions/revisions)

"Computer software (or simply software) refers to any of the various programs by which a computer controls aspects of its operations, such as those for translating data from one form to another, as contrasted with hardware, which is the physical equipment comprising the installation. The term is roughly synonymous with computer program but is more generic in scope. In most computers, the moment-to-moment control of the machine resides in a special software program called an operating system, or supervisor. "

Multivariable controls is a field of control theory that delas with systems that have more than one input and output.  Unlike classical control theory, which deals with single-input, single output (SISO) systems, multi-variable controls defines methods for mult-input multi-output (MIMO) systems.  The theory addresses many issues, including controlability, stability and design of control systems.
