【Abstract】 A digital current control strategy of PMSM applying space vector modulation (SVM) is studied, and an all-digital AC software servo drive system based on 16-bits singlechip computer is presented. In the system, the capacity of driving load can be improved by employing robust current control technique and current prediction technique is adopted to shorten the dead time of current control, which improve the performance of current control apparently. Simulation and experiment results verify the new current control method valid.更多还原
