Abstract
The vector control system for induction motor used in electric vehicle was analyzed. A parameter identification and optimization algorithm for induction motor was proposed. Two different kinds of frequency sine signals generated by sinusoidal pulse width modulation were injected into the motor respectively, to identify the rotor resistance, mutual inductance and leakage inductance. On the d-axis, a sinusoidal current with DC bias was applied while the q-axis current was controlled to be zero, to optimize the rotor resistance. A step signal was injected into the induction motor to optimize the rotor time constant . The experiments of parameter identification and optimization using the algorithm were carried out on the 7. 5 kW induction motor. All conclusions indicate that the identification and optimization results are correct.关键词
