摘要
In motion control, position control systems for servomotors are generally designed without considering, the current loop and the dynamics of a PWM inverter. In this paper, a novel precise model of a servomotor is developed, including the current loop and the PWM inverter, and a high-speed servo system is proposed based on perfect tracking control with the precise model. Finally, simulations and experiments are performed to show the advantages of the proposed method. (C) 2008 Wiley Periodicals, Inc.
