10 N?m。 According to the response characteristics of the load torque to the external input voltage by the eddy current dynamometer, the dynamic matrix for predictive control of the eddy current dynamometer was established. The parameters of the dynamic matrix control (DMC) were tuned by adopting genetic algorithm. Based on the research of the mechanical characteristics of the eddy current dynamometer, the application of the dynamic matrix predictive control method on the eddy current dynamometer was studied subsequently. The simulation results show that the time consuming of raising the turning torque from zero to 320 N?m is about 800 ms by using the DMC controller based on the genetic algorithm. The efficiency is improved by 60% and the torque error is 10 N?m under stability control.  
