Based on analyzing air-gap-flux orientated control based vector control drive for electrical excited synchronous motor,a control strategy based on power-angle closed-loop is proposed and the theoretical basis of this control strategy is presented in detail.This strategy contains the power-angle closed-loop control strategy brings the influence to vector control for synchronous motor and mathematical observation model of power-angle is constructed,and the control system is simulated under steady-state operation and load mutation.The experimental results indicate that the strategy based on power-angle closed-loop of vector control has fast response and short adjustment time.The air-gap-flux orientated control based vector control drive for electrical excited synchronous motor,using the control strategy,possesses acceptable static and dynamic performance.
