摘　　要：基于永磁同步电机d、q坐标系电流模型,运用自适应方法和稳定性理论,在模型参数未知的情况下,设计一种参数自适应电压矢量控制律,该控制律利用d、q轴电流误差、模型的估计参数等信息,通过引入误差反馈补偿、参数估计补偿等方式消除d、q电流的控制误差,并通过参数自适应律消除模型存在未知参数带来的影响,特别是有效处理控制输入存在乘积因子未知的情况,较传统的PID控制方法提高了环路控制的性能,通过仿真验证了该控制律的有效性。A voltage vector control algorithm was designed under the condition that the model parameters were unknown,based on the current model of permanent magnet synchronous motor in d and q coordinate system and using the adaptive method and stability theory.The control algorithm contains the current error information of d and q axis and can eliminate the steady-state error and improve the rapidity of current control by introducing error feedback compensation and parameter estimation compensation.Furthermore,the influence of unknown parameters was eliminated by the parameter adaptive law.The control algorithm can improve the control performance comparing with the traditional PID control method,which can be verified by simulation.
