Abstract

This paper proposes a disturbance suppression control with preview action for brushless & coreless type linear DC motor. Brushless & coreless type linear DC motor is coggingless and has long life. It is suitable for high speed and precise positioning control. Parameter variation and load change are regarded as equivalent disturbance signal and the compensation action is applied by utilizing the estimated value of the equivalent disturbance inside the inner loop. Next, Optimal preview control system is synthesized including the disturbance suppression control system mentioned above. Disturbance suppression, improving of phase delay and lowering of input peak value are attained in this control system. These effects are confirmed by applying the linear DC motor.
