Compound control for brushless DC motors using cerebellar model controller and PID controller

To improve the performance of brushless DC motor drives, a novel approach of compound control for brushless DC motor using cerebella model articulation controller and PID strategy was proposed. The principle of cerebella model articulation controller was introduced. The structural flow chart of control system was presented. The compound control algorithm was discretized to be implemented on digital control systems. The operating condition with speed reference and torque reference changed was simulated and experimented. The proposed intelligent control strategy shows perfect response on speed reference with very short setting time and extremely reduced overshot. The effect of load disturbance is dramatically restrained. Motor speed traces reference steadily and accurately. Finally, conclusion can be drawn that the intelligent control strategy is better than PID control both in dynamic and steady state.
