Robust Control Of Brushless Dc Servo Motor Using Dual Passive Adaptive Control Loop

This paper proposes a new linear adaptive drive system of brushless DC servo motor. The proposed method can rapidly reject the state error caused by both parameter variations and force disturbance. The structure of this adaptive control method is based on the dual passive adaptive control loop. The drive system using this dual loop can realize the strictly robust control of brushless DC servo motor. Numerical and experimental examples show that the proposed method is effective for suppression of parameter variations and force disturbance.
