基于广义预测控制的无刷直流电机控制研究

Under the circumstance of high control precision and quick response of speed, it is difficult for traditional control method to control brushless dc motor（BLDCM）well. This paper introduces a method of Generalized Predictive Control (GPC) for brushless dc motor which designs double closed loops structure of BLDCM control system. Outer ring is GPC speed controller whose control objects are the motor and the inverter. Given speed, real-time speed, real-time current are inputs. And the output of current value is the input of the inner ring. Inner ring controller uses the current hysteresis control whose output is the input of inverter module. After running Matlab simulation model, GPC is proved to have low requirements for model, strong anti-interference and good control effect.?????
