Process control introduction
1. Process control is important for modern food processing industries to improve economics, ensure safety, reduce variation, waste, and maximize efficiency.
2. Accurate measurement of process parameters like temperature, pressure, and material levels is critical for control. Sensors can be penetrating, sampling, or nonpenetrating.
3. Control systems can be manual or automatic using control loops with sensors, controllers, and final control elements. The most common automatic controllers are on/off, proportional, proportional integral, and proportional integral derivative controllers.
Process control
This document provides an introduction to process control. It defines a process as an operation that transforms raw materials into a more useful state. The objectives of process control are to produce desired outputs from inputs in the most economical way. Processes can be described by differential equations and are affected by various internal and external conditions. Effective process control requires maintaining safety, meeting production specifications, and optimizing economics while addressing changing external influences. Examples of processes include unit operations in chemical plants and manufacturing units. The document outlines the basic components of a process control system and loop.
Process control examples and applications
Process control involves maintaining the output of a process within a desired range through mechanisms and algorithms. For example, controlling the temperature of a chemical reactor to maintain consistent product output. There are different types of process control including regulatory control to maintain performance at a certain level, feedforward control which anticipates disturbances to compensate before they affect the process, and adaptive control where the controller modifies its own parameters based on dynamic process conditions. Discrete control systems make event-driven or time-driven changes to processes.

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Process Control
- 2. Process Control What is Process Control ? - Process control is the use of computers or microprocessors to control a process. Process control is used in oil refining, chemical processing, car manufacturing, and temperature control, as well as the food and beverage industries.
- 3. There are three types of process control :- 1) Batch process control. This is used in processes where specific amounts of raw materials are combined together and mixed for a certain length of time. An example is the manufacturing of food products such as pre-packaged meals. The ingredients are measured into a large vessel and mixed together for a certain amount of time. They are then heated to cook them. The amount of each ingredient that is added is controlled by computer, as is the length of time for each stage and the temperature. Batch processes are generally used to produce relatively small amount of product per year.
- 4. Example of Batch Control System Manufacturing of food products
- 5. 2) Continuous process control. Often, a physical system is represented through 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).
- 6. Example of control system of a continuous stirred-tank reactor.
- 7. 3) Discrete process control. This is when specific items are produced. 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.
- 8. Discrete process control such as the wheel fitter
