无轴承永磁同步电主轴的模糊滑模位移控制
Fuzzy Sliding Mode Displacement Control of BPMSMS
摘要
Abstract
To meet the requirements of high performance rotor displacement control of bearingless permanent magnet synchronous motorized spindles,and by integating the advantages of fast genetic algorithm and softening control signal,a rotor displacement control strategy which organically combines sliding mode equivalent control,fuzzy control and genetic algorithm is proposed.The fuzzy switching gain is introduced in the sliding mode control.The fuzzy sliding mode controller parameters are optimized by genetic algorithm to obtain the best control effect.The results show that the fuzzy sliding mode control reduces the chattering of the system under the traditional sliding mode control.The peak-to-peak values of different axial steady-state rotor vibrations under fuzzy sliding mode control optimized by the genetic algorithm are reduced by 53％and 27.5％respectively.关键词
