Damping of the oscillatory system is the effect of preventing or restraining or reducing its oscillations gradually with time. The damping ratio in physical systems is produced by the dissipation of stored energy in the oscillation. It is the restraining or decaying of vibratory motions like mechanical oscillations, noise, and alternating currents in electrical and electronic systems by dissipating energy. Examples of damping are; viscous drag in mechanical systems, resistance in electronic … [Read more...]
What is Distributed Control System : Working & Its Applications
In the initial days, the process of controlling for giant industrial purposes is so difficult and developed after multiple phases. Originally, the controlling requires panels for processing of plants and this needs a huge workforce too and even this provides no exact results. And the next advancement is the transformation of all plant measurements into a permanently controlled central room where acts as the centralism of entire localized panels providing the benefit of less workforce. But seems … [Read more...]
Difference between Open Loop & Closed Loop Control System
In 1767, James Watt's Flyball governor invented a device called a control system to control the constant speed of the engine with the regulation of the speed of the steam supply to the engine. When the output of the system is regulated or controlled by varying the input, then such a type of system is called a control system. The function of the control system is determined by the differential equations (ordinary or difference equations). It can manage, command, direct and regulate the function … [Read more...]
Traffic Light Control System using Microcontroller
Traffic lights were first invented in the year 1868 at London’s House of Commons where traffic light signals were placed at intersections of George and Bridge Street. Later the traffic lights were developed in the year 1914 by an American Traffic Signal Company, which fixed green and red lights at corners of the 105th street and Euclid Avenue in Cleveland, Ohio. During this period traffic lights were controlled either by timing or by switching manually. … [Read more...]
What is an Open Loop Control System & Its Working
The collection of subsystems that controls the input signal to get the desired output is known as a system. The main function of any electronic system is regulating the output and keep that within systems desired input i.e when the input of the system changes, the output of the system should respond and change according to the changed input value. In another case, if there is no change in input but the output of the system is getting disturbed then the output should respond by coming back to its … [Read more...]
