Research on Efficiency Optimization of Interior Permanent Magnet Synchronous Motor Based on Intelligent Integrated Control

摘要：

To improve the steady state efficiency of interior permanent magnet synchronous motor system(IPMSM), the intelligent integrated online optimal control strategy of IPMSM efficiency optimization was presented. The intelligent integrated control technology and torque compensation method were combined to the system. The method of adaptive fuzzy logic to adjust direct-axis current was adopted in the first half search, using the adaptive step size to reduce the torque fluctuations. The golden section search method was adopted in the next half search to speed up the search process and improve its convergence. While in the whole process, the torque correction program was introduced to compensate the torque current in real-time and resolve the torque pulsation problem in the regulation process of the excitation current. The dynamic and static performances of the system are improved. A 100kW IPMSM efficiency optimization intelligent integrated control system was implemented using a TMS320LF2407A DSP. Experimental results prove the validity of the proposed strategy.
