An old streetlight contactor / relay was used in this example with the control system: A control system is a set of mechanical or electronic devices that regulates other devices or systems by way of control loops . Typically, control systems are computerized.

    On-Off control is the simplest form of feedback control. An on-off controller simply drives the manipulated variable from fully closed to fully open depending on the position of the controlled variable relative to the setpoint. A common example of on-off control is the temperature control in a domestic heating system.... Control systems this crude usually provide very imprecise control of the process variable. Consider our example of the shell-and-tube heat exchanger, if we were to implement simple on/off control: As you can see, the degree of control is rather poor.

    Fig. 1-1. Basic components of a control system. Open-loop systems: The open-loop system is also called the non-feedback system. This is the simpler of the two systems. A simple example is illustrated by the speed control of an automobile as shown in Figure 1-2. In this open-loop system, there is no way to ensure the actual speed is close to the The CN1A Series is a digital On/Off temperature controller designed to provide the functionality of general purpose PID controllers but at a price suited to On/Off applications. The simple programming with two front panel keys, uncluttered LCD display, and uncomplicated control functions and alarm programming have enabled the CN1A to be widely

    Example of a real time system is - a process control system. In a process industry the process parameters like temperature, flow, or pressure or status of a device (say a valve open or close) are Examples from Other Courses.

    A block diagram depicting a multivariable control system is shown in Figure 1.4. A common example of an open-loop control system is an electric toaster in the kitchen. An example of a closed-loop control system is a person steering an auto-mobile (assuming his or … These modern industrial control systems are usually made to produce one or more control actions depending on the application implemented. This article describes the basic control strategies used in industrial control system and its types with a brief explanation. Introduction to Industrial Control Systems

    On off control system example

    INSTRUMENTATION AND CONTROL TUTORIAL 4 – SYSTEM RESPONSE This tutorial is of interest to any student studying control systems and in particular the EC module D227 – Control System Engineering. On completion of this tutorial, you should be able to do the following. Explain the output response of an ON/OFF control system. The open-loop plant model. In the Introduction: Simulink Modeling page we demonstrated how Simulink can be employed to simulate a physical system. More generally, Simulink can also simulate the complete control system, including the control algorithm in addition to the physical plant.
