Abstract This paper summarizes the theory and algorithm of indirect vector control step by step. Based on this, then the decoupling control variations of electromagnetic torque and rotor flux linkage in the torque control loop caused by motor parameters detuning are mathematically deduced and analyzed in detail. The detuning curves are derived by using Matlab programming language, open and close loop of electromagnetic torque and rotor flux linkage parameter sensitivity, as well as maximum torque characteristics are given. The results achieved from this paper can give a reference to the asynchronous motor vector control system design, especially parameter estimation and compensation, without complex calculation.
