摘　　要：提出了一种永磁同步电动机实时自适应电流控制方案，在预测电流控制的基础上增加参数辨识，以克服电动机参数不准确带来的影响．用比较计算模型和实际电动机输出之间差别的方法对电枢电感和磁通进行辨识。A real time adaptive current controller for a drive system with a PWM inverter fed permanent magnet synchronous motor is presented. The current control scheme proposed is based on predictive current control but with an identification algorithm added in order to compensate for the inaccuracy of the motor parameters. The parameters of armature inductance and flux linkage are identified by comparing the difference between the outputs of the calculation model and the actual motor. A DSP based implementation scheme is presented. Experimental results are given.
