N2 - Since permanent magnet synchronous machine (PMSM) control based on zero-order hold (ZOH) discretization can achieve better performance under low carrier ratio, it has attracted widespread attention from both academia and industry. However, due to its complex structure and the involvement of exponential calculations, the discrete-time current control difficultly conduct in low-cost microprocessors. Aiming to solve this issue, a simple discrete-time current control based on current measurement error is proposed, where the current performance of command tracking and disturbance rejection capabilities are enhanced. To verify the effectiveness, corresponding experimental results are carried out in a 750 W PMSM drive test rig.
