Abstract: Abstract:In order to improve the maximum rotation angular velocity of electromechanical actuator (EMA) under the light load condition and inhibit the load disturbance, the fluxweakening algorithm for SPMSM adaptive speed adjustment is proposed on the basis of space vector pulse width modulation (SVPWM). Firstly, the speed is improved by the fluxweakening algorithm based on physical power limit, when the power of the system is surplus. Then, for the traditional PI algorithm has the disadvantage of weak dynamic performance when load is changeable, a speed adaptive controller based on Lyapunov stability is presented. Finally, it is proved that the algorithm can realize fluxweakening speed growth, and a good performance of load disturbance inhibition by Simulink simulation.
