| 摘 要： | 无论电机的转速高低和电机参数的大小，都可以通过计算交叉项得到准确的d、q轴电压给定值，从而准确地控制d、q轴电流,提高d、q轴电压控制精度.为此，根据永磁同步电机转子磁场定向的矢量控制理论，在分析传统控制方法存在问题的基础上，提出了一种在d、q轴电压控制方程式中引入交叉耦合项的改进的矢量控制方法,使控制系统在较宽的速度范围内能满足较高的速度控制精度要求，使永磁同步电机伺服系统可实现准确的位置、速度及转矩控制.利用所提出的控制方法，进行系统仿真研究，表明了所提出的控制策略的有效性.

| Abstract: | No matter what change of motor speed and parameters is,the given voltage and current of d-axis and q-axis can be obtained accurately by calculating cross-coupling terms,and the precision of voltage is improved.Based on the conventional theory of rotor field-oriented vector control for permanent magnet synchronous machine(PMSM),an improved vector control strategy with cross-coupling terms is presented.By adopting the improved vector control strategy,the speed control precision is enhanced in a wider speed range,and rotor position,speed and torque control for PMSM are implemented. Simulation is conducted and the obtained results verify the validity of the proposed control strategy. |
