摘　　要：在分析气隙磁链定向控制的电励磁同步电机矢量控制原理的基础上,提出了一种基于功角闭环控制的矢量控制策略.阐述了功角闭环控制策略的原理,包含功角闭环控制策略给同步电机矢量控制带来的影响以及功角观测模型的构建,并在稳态运行与负载突变2种条件下对控制系统进行了仿真实验.实验结果表明:基于功角闭环控制的矢量控制策略响应速度快、调节时间短.以此控制策略实现的电励磁同步电机按气隙磁链定向的矢量控制具有良好的静、动态运行特性.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.
