Abstract：The existence of time-delay constrains the performance of vector controlled inverters, particularly has a deep influence on high power and low switching AC drive converters, which may result system instability when motor is running in middle or high speed. The relationship between time delay and system stability is analysised. A new time delay compensation algorithm based on q-axis current error is proposed, which overcome the limitations of traditional compensation system, and which is realized simply. At the same time, this compensation algorithm eliminate current oscillation and motor unstable speed swing in middle-high speed. At last, the proposed time delay compensation algorithm is varified on 110kW AC induction motor vector control experiment platform.
