Abstract :
The parameters variation of electric vehicle induction motor drive system will directly affect the implementation effect of efficiency optimization control strategy. An efficiency optimization strategy based on loss model is given at first, the relationships between the algorithm parameter-dependent and the motor speed are discussed based on the parameter sensitivity analysis then, and the influence of iron loss equivalent resistance variation and magnetic saturation nonlinearity on efficiency optimization control are analyzed in details. The experiment system is built with DSP TMS320LF2407A, the experimental results verify the validity of the analysis. It provides a sound practical guidance for efficiency optimization control implementation of electric vehicle propulsion system.
