N2 - Efficiency optimization control of salient pole permanent magnet synchronous motor (PMSM) based on maximum ratio of torque to current is presented. From basic equations of PMSM in d, q reference frame, the method of maximum ratio of torque to current was derived using maximum principle. Then, based on the Least Squares Support Vector Machine (LSSVM), modeling of LSSVM controller of maximum ratio of torque to current by using simulation data. The simulation result shows that LSSVM has a good generalization ability and capability of modeling nonlinear process, and the original sampling data are very similar to the data predicted by LSSVM model. And using method of LSSVM maximum ratio of torque to current, the simulation of PMSM shows that the PMSM control system has a good dynamic ability and achieves efficiency optimization control.
