基于滑模控制的混沌系统在永磁同步电机中的应用研究

Applied Research of Chaotic Systems in Permanent-magnet Synchronous Motor Based on Sliding Mode Control

将基于滑模控制的方法应用于永磁同步电机(PMSM)混沌系统中。为了在滑动模态中保证系统的同步性能,采用一种新型的比例积分切换面。基于滑动模态的控制器具有鲁棒性,即使在参数不确定和外部干扰存在的情况下,也能保证滑动模态的出现。通过分析高复杂性的动态非线性系统——混沌系统,来研究鲁棒的同步性问题,并在滑动模态下,通过选择适当的反馈阵,采用任意极点配置法来设置系统的动态误差特性。仿真结果表明控制设计方法实现简单并且性能优良。

Sliding mode control （SMC） method ic systems. A novel proportional-integral （PI） performance of system in sliding mode motion. was applied in permanent-magnet synchronous motor （PMSM） chaotswitching surface was introduced for determining the synchronization Based on the sliding mode controller, it was established by a robust control scheme which guaranteed the occurrence of a sliding motion of error states even when the parameter was uncertain and external perturbation was present. The robust synchronization problem was researched by analyzing a highly complex dynamic nonlinear system-chaotic systems, and in sliding mode, the performance of error dynamics was assigned by selecting an appropriate feedback matrix using any pole assignment method. The simulation results demonstrate that the control design process is easy to complete and the system has a good performance.
