“…According to (14), under the condition of inductance mismatch, q-axis current error is caused by the nonzero d-axis current. For surface mounted PMSM, the motor torque is not directly related with i d , so introducing error integration in d-axis current control is the easiest way to eliminate current error caused by inductance mismatch, without impairing the dynamic response of current control:…”

This paper presents a novel algorithm to eliminate d-q axis static current error of PMSM predictive current control when the model in predictive controller has parameter mismatch with real system. The relationship between current error and parameter mismatch is analyzed numerically, and the static current error is eliminated by introducing current error integration in d-axis current control while dynamically adjusting the parameter of controller flux according to the q-axis current error. The algorithm is quite suitable for industrial application and is verified through simulation and experiment on a 3.3kW PMSM servo platform.

This paper presents an algorithm to eliminate the static error of PMSM predictive current control when the model in controller has parameter mismatches with real system. The algorithm mainly applies to cases where the controller inductance is smaller and the controller flux is not accurate. The static error caused by smaller inductance is eliminated by introducing error integration in d axis current control. The error caused by flux inaccuracy is eliminated by dynamically adjusting the flux parameter according to q axis current error. The algorithm is verified through simulation and experiments on a 3.3kW PMSM servo platform.

The virtual resistance technique has been widely adopted to improve the disturbance rejection of the complex vector decoupling approach for surface-mounted permanent magnet synchronous machines at high speed. Its gain selection, however, has only been discussed in the continuous domain. In this study, the virtual resistance technique is analysed directly in the discrete domain. Theoretical analyses demonstrate that there is a definite upper limit for the virtual resistance selection which is only dependent on the ratio between the time constant of the machine and the sampling period. A new discrete current controller is proposed to improve the command tracking and the disturbance rejection of the current loop. A trade-off is made between the rapidity and the robustness of the proposed controller in order to achieve a parameter error tolerance of 50%. Experimental results verify that the proposed controller gains better performance at high speed, i.e. a higher bandwidth of 0.135f s without overshoots and fewer oscillations, than the controllers designed in the continuous domain. Even deadbeat responses, to both the reference signals and the disturbance, can be achieved by the proposed controller at its limits.
