Process control is used in the industry allowing mass production of consistent products like chemicals, paper production, oil refining, power plants and other. It turns a heating system on and off based on signals it receives from sensors that monitor air temperature. Infrared sensors can detect objects in front of it. Unlike a centralized control system that operates all machines, a DCS enables each part of a machine to have its own dedicated controller that runs the operation. At a high level, access control is a selective restriction of access to data. Feedback Control System (Photo by Author) State- output produce by a robotic system is known as a state.Normally we denote it by x, the state depends on its previous states, stimulus (signals) applied to the actuators, and the physics of the environment.The state can be anything pose, speed, velocity, angular velocity, force and Automobile cruise control . Like DCSes, PLCs are used in ICSes for a variety of industries. We will vary this input with some mechanism. The loom invented by Joseph Jacquard of France in 1801 is an early example of feedforward; a set of punched cards programmed the patterns woven by the loom; no information from the process was used to correct the machines operation. Control Systems can be classified as open loop control systems and closed loop control systems based on the feedback path. Control action is dependent of the desired output.
