A servo motor based robotic arm is designed for collecting soil sample and test various soil parameters. A closed loop feedback algorithm based on Digital PID controller has been developed for precise ...

This article explains proportional integral derivative (PID) control, including the math behind it, with the use case of a linear servo motor.

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.

The DC motor speed can be set for open or closed loop with preset current/torque levels or the motor torque and direction can be set with analogue inputs.

Significant research work has been carried out to improve the performance of closed loop response with PID controller so that it can be used for real time temperature control system using SCADA ...
