Abstract :
This paper presents an improved stator flux orientated (SFO) control strategy of induction motors. Based on coordinate transformation and stator flux orientation, a mathematical model of induction motor is derived. In this new system, the stator flux linkage is directly controlled by the d-axis component of stator voltage and in the speed control channel, the output of current controller is regarded as slip frequency, which inherits the advantages of ordinary slip frequency control schemes. System control algorithm is independent of rotor resistance and all inductance parameters. Simulation and experiment results prove that this new system displays high static/dynamic performances and robustness
