摘要：In this paper, the electromechanical coupling model of a tumble washing machine's drive and vibration attenuation system is put forward. In order to avoid complexity of the traditional dynamic analysis method, a method which adapts rotary reference coordinate system is presented. By analyzing the electromechanical coupling in electromechanical system, it is found that the output of the system has an influence on the drive current and output torque of motor. Rest on this relation, the active control of washing machine's drive and vibration attenuation can be achieved. This paper makes some exploration in applying nonlinear feedback decoupling control strategy to a factual system, in which two control variables Vq and Vd are employed, observers of torque disturbance and vibration amplitude are proposed, new control algorithms is put forward. In this paper, the simulation model based on computer simulation is also built, and some valuable results have been acquired. Comparing with conventional control strategy, the nonlinear feedback decoupling control strategy achieved more satisfying effect. © 2003 IEEE.
