Abstract：The efficiency maximization control condition for PMSLM vector control is studied and analyzed for the problem of efficiency of the motor drive system. The system loss model considering the inverter loss is established through analysis of the loss model of the permanent magnet synchronous linear motor (PMSLM). The efficiency maximization control condition for PMSLM vector control drive at steady state condition is derived using lagrange theorem. To make the system has better robustness, the fuzzy controller of efficiency based on the system loss model is designed. The experimental results show that the proposed model is accurate at steady state by Matlab/simulink.While keeping the output-power constantly, the purpose that rapidly reached the efficiency maximization can be achieved.
