摘要
随着矢量控制技术的发展,如何对矢量控制系统进行优化已成为热门课题。分析了基于转子磁场定向矢量控制的原理,建立了基于SVPWM和模糊自适应PI调节器的异步电机矢量控制系统模型。采用Matlab/Simulink对该系统进行了仿真实验。仿真结果表明,该系统的电压利用率高,能有效抑制转矩脉动,具有良好的适应性和鲁棒性。
With the development of vector control technology, how to optimize vector control system has become a hot topic. The principle of rotor field orientation-based vector control＇ is analyzed, and the asynchronous induction motor vector control system model based on SVPWM and fuzzy self-adaptive PI regulator is built. In addition, a simulation test is performed on the system with Matlab/Simulink software. The simulation results confirm that the system has high utilization ratio of voltage, well efficiency in torque ripple minimization, good adaptability and robustness.
