Under the influence of variable load,permanent magnet synchronous generator is prone to have fuzzy control threshold behavior,which affects the stability of the electromechanical system.A chaos control method for variable speed permanent magnet synchronous generator is designed under variable load.By simplifying the parameters such as stator current and stator voltage,the dynamic process of converting mechanical energy into electrical energy is used to calculate the magnetic flux of the motor.The magnetic flux is applied to establish the control fundamental wave of synchronous generator in real-time state.According to the mapping range of chaos algorithm,the excitation control law of different chaotic behaviors under variable load is output to realize chaos control of variable speed permanent magnet synchronous generator.The experimental results show that under pure resistance load and pulse load,the proposed method has no phenomenon of increasing current and voltage rise rate and the controlled engine rotor angle is consistent with the initial angle,which has good control ability.
