PID control The PID controller has been in use for over a century in various forms. It has enjoyed popularity as a purely mechanical device, as a pneumatic device, and as an electronic device. The ...

New ISA technical report distills thousands of pages of PID references for improving process performance. Even though controllers using the proportionalintegral-derivative (PID) algorithm have been ...

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.
