摘要
永磁同步电机运行系统中表现为间歇性振荡和不规则电磁噪声的混沌行为会对系统运行的稳定性造成较大程度上的损害。针对该种混沌现象,通过时间尺度变化和线性仿射变化将永磁同步电机的运动模型转换为一个三阶的无量纲化非线性方程组,采用定参数分析法对气隙均匀条件下永磁同步电机的无量纲模型进行分析,使得系统参数由小到大变化,发现在一定的范围内,系统将进入混沌运动状态。通过构造滑模函数设计一种动态滑模补偿混沌控制算法,基于LMI算法分析证明了其理论有效性。仿真实验结果验证了系统采用动态滑模补偿混沌控制算法后,具有良好的鲁棒性和快速的动态响应性能。
The chaotic behavior of intermittent oscillation and irregular electromagnetic noise in the operation system of permanent magnet synchronous motor will cause great damage to the stability of the system operation.Aiming at the chaotic motion behavior of permanent magnet synchronous motors,the motion model of permanent magnet synchronous motors was converted into a third-order dimensionless nonlinear equation group through time scale changes and linear affine changes.The dimensionless model of the permanent magnet synchronous motor was analyzed under the condition of uniform gap,and it is found that the system will enter a chaotic state within a certain parameter range.In order to suppress the chaotic behavior of permanent magnet synchronous motors,a dynamic sliding mode compensation chaos control algorithm was designed by constructing a sliding mode function,and its theoretical validity was proved based on the analysis of the LMI algorithm.The simulation test results verify that the system has good robustness and fast dynamic response performance after using the dynamic sliding mode compensation chaos control algorithm.
