A New Efficiency Optimization Method on Vector Control of Induction Motors

A new efficiency optimization method on induction motor control which does not require extra hardware and is insensitive to motor parameters is presented in the paper. The relationship between the stator current minimum and the loss minimum in the vector control system is investigated. A fuzzy logic based search method is implemented by TMS320F2812 fixed-point DSP. Simulation and experimental results are presented in the paper to verify the effectiveness of the proposed approach
