Abstract:
Motion control usually includes the precise control of
position/velocity and acceleration control while accurate
acceleration control is not useful in many applications.
Traditional position/velocity control is derived by feedback
based, PID controllers. However the disturbance observer
further increases the stability and robustness of the controller. In
this paper we assess the effectiveness of the Disturbance
Observer working together with a tuned PID controller. Velocity
response is compared with and without the disturbance observer.
The proposed disturbance observer based velocity controller
produce better results than the traditional velocity controller.
