Proportional-Integral-Derivative (PID) Control Systems
Proportional-Integral-Derivative For processes that are able to operate with continuous cycling, the relatively inexpensive two position controller is sufficient. For processes that cannot tolerate continuous cycling, a proportional controller is used. For processes that tolerate neither cycling nor offset error, … Read more

Pulse Width Modulation (PWM) Speed Control of a DC motor
We can control the speed of a motor using an open loop control or closed loop control strategy. The open loop control is the simplest form of motor control; here we simply set the drive voltage value and the motor … Read more

The Operation of a Temperature Control System for lubricating oil
A lubrication oil temperature control system Lubrication oil temperature control system block diagram Lubricating oil reduces friction between moving parts and also removes heat from the components. As a result, the oil becomes hot. This heat is removed from the … Read more

Feedback Control System
The basic elements of a feedback control system are represented by the block diagram below. The functional relationships between these elements are also shown in the diagram. Feedback Control System block diagram The block diagram represents flow paths of control … Read more

Principles of Control Systems
A control system is a system of integrated elements whose function is to maintain a process variable at a desired value or within a desired range of values. The control system monitors a process variable or variables, and then causes … Read more
