摘要
The dual-mode operation and smooth transition control of the high-speed permanent magnet synchronous motor(HS-PMSM) is proposed based on the sinusoidal-wave and square-wave driving modes.Based on the equivalent hardware configuration of the HS-PMSM drive,typical space vector pulse width modulation(SVPWM) strategy is introduced for the sinusoidal-wave drive(SINWD).The adaptive neural network(ANN) inverse system method and the two degrees of freedom internal model controller(2-DOF IMC) are combined as the speed loop controller of the square-wave drive(SQUWD).To achieve the smooth transition,the switch signals for the transition point are studied.The effectiveness of the proposed control scheme is validated by the simulation results.
