Driving Control Research of Less-rare-earth Tooth Yoke Magnetomotive Complementary Doubly Salient Permanent Magnet Motors Based on Resonance Compensation Strategy
摘要
Abstract
In this paper,taking a less-rare-earth tooth yoke magnetomotive complementary doubly salient permanent magnet motor as a study object,proposed an effective resonance compensation strategy to achieve speed ripple suppression and motor drive performance improvement.Firstly,the harmonics of back-EMF and cogging torque were analyzed,and then the torque equation and motion equation were further deduced based on the analysis results.Then a current adjust method which combined the PI controller and the resonance controller was proposed,and the improvement scheme was determined to promote the effect of speed ripple suppression as possible based on the sinusoidal periodical characteristics of speed ripple.The system simulation model is built in Matlab according to the resonance compensation strategy,the characteristics of speed ripple with and without compensation strategies were analyzed by simulations.The results of analysis and simulations were verified by experiments on the prototype.Finally,the simulation and experimental results show that the presented resonance compensation control strategy can suppress the speed ripple of the motor effectively and promote the operation performance.关键词
