一种抗高过载电机设计与控制策略研究
Research on design and control strategy of anti-high overload motor
摘要
Abstract
In order to solve the problem of vulnerability of the missile-loaded motor in the high overload environment of 23 000g guided artillery projectile,the anti-high-overload brushless DC motor using a combination of disc spring and special steel ball for buffering and vibration damping is designed,and a sensorless observation method based on high frequency injection of pulse vibration and fuzzy super-twisting sliding mode observer is proposed.Considering the interference factors such as high frequency,friction,and wind resistance during the guidance process,which affect the fast response and high-precision control of the missile borne motor,a super-twisting sliding mode active disturbance rejection control strategy is proposed.The results of simulation and motor experiment results show that the rotor position tracking error of sensorless observation method is only 0.008 rad.In comparison with traditional active disturbance rejection control,the response speed of the proposed control strategy is improved,the speed oscillation is reduced from 0.5 r/min to 0.1 r/min,and the disturbance rejection ability is enhanced by about 1 time.关键词
