Program Plan Intro
PID Control:
- The Proportional Integral Derivative (PID) control refers to a feedback control method.
- It performs the combined actions of proportional, integral, and derivative controls.
- It is one of the most widely used process controller.
- The PID control is used to maintain a process variable within the limits of a specified set point. These process variables can be temperature, flow, level, or speed.
- It also allows the control process operations to take place outside the Central Processing Unit (CPU), which in fact, greatly reduces the additional burden of CPU.
