摘要
近年来分数阶微积分理论在永磁同步电机(PMSM)中的应用得到广泛研究。PMSM是典型的多变量耦合、非线性系统,且其运行过程中存在参数摄动和负载扰动。为提高PMSM的动态性能以及对负载扰动的鲁棒性,设计了基于改进型指数趋紧率的PMSM分数阶滑模控制器(FOSMC)。构建了硬件在环实时仿真试验系统,然后在Simulink/Qua RC环境下,对所设计的控制器进行试验验证,并和传统整数阶滑模控制器(SMC)做了性能比较。试验结果表明,所设计控制器具有良好的动态性能,且可以减少系统抖振,并对负载扰动具有更强的鲁棒性。
Recently the application of fractional order calculus in permanent magnet synchronous motor （PMSM） has been widely researched. The PMSM is a typical multivariable coupled and nonlinear system, and the parameters perturbation and load disturbance exist in the PMSM system. In order to improve the dynamic performance and robustness of the PMSM control system, the fractional order sliding mode controller （FOSMC） with modified exponential reaching law was designed. The Hardware-in-Loop real time simulation system was constructed, and then the effectiveness of the FOSMC method was tested and compared with the conventional sliding mode controller （SMC） in the Simulink/QuaRC. The experiment results show that the proposed method has excellent dynamic performance, decreases the system chattering, and is more robust to the load disturbance.
