Understanding Control Systems: Proportional, Integral, Derivative & More
Understanding Control Systems
Proportional Control
A proportional (P) control system responds to an error signal, providing a symmetrical correction proportional to the error. A constant error signal results in a constant corrective action. Sudden changes in the error signal lead to a fast response from the controller.
Proportional-Integral Control
In proportional-integral (PI) control, the error signal causes a growing response due to the integral action of the controller. This type of control is suitable
