| Abstract: | This paper deals with LQSF DC speed regulating system with an observer of disturbance and speed employing single board computer TP801B. The observed values from the observer of disturbance and speed have been fed forward and fed backward respectively. The results of experiment have Shown that the system can provide short starting time without speed overshoot, better dynamic characteristics and zero steady state error when there exists load disturbance,. Also it is easy to change the parameters of this kind of digital control system. |
