Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. Synchronous dc motors often top the field in high-performance motor controls. This group of ...

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.

Many of us will have experimented with brushless motors, and some of us will have built our own controllers rather than using an off-the-shelf part. Doing so is a good way to understand their opera… ...

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

Amazingly, to this day, there are still a very significant number of analog PID controls sold every year. Because of its simplicity, many robot designers have adapted software PID controls for servo ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies.
