摘要

In order to eliminate steady-state speed error of PMSM backstepping control system,an integral backstepping speed control algorithm is designed in this paper.By adding speed error integral factor in the speed Lyapunov function,the speed error can finally converge to zero when PMSM operates in steady-state.On this basis,an integral backstepping speed control algorithm based on RBF neural network compensation is proposed for PMSM backstepping control system used for high-altitude electric propulsion system which is vulnerable to load torque variables.The integral backstepping speed controller based on PMSM reference model can ensure global asymptotic convergence of the whole control system.In order to achieve fast robust adaptive control,the RBF neural network is adapted to online compensate dq axis current error produced by the reference speed and load torque changes.Simulink simulation results verify the feasibility of the given algorithm.
