Why is it important?

The double integral sliding-mode controller (DISMC) can reduce the steady-state errors more effectively for brushless DC motor speed control. And an adaptive PID observer is also developed for the DISMC scheme to on-line adjust the control gains, thereby achieving favorable tracking and regulation performance.

Perspectives

This article attempts to use different methods to increase the accuracy and stability of the brushless DC motor speed control, digital signal processor is also very easy to achieve, it is worth the motor control designer's reference.
