永磁同步电动机混沌系统的控制研究

Permanent Magnet Synchronous Motor Chaotic System Control Research

采用输入-状态线性化方法控制永磁同步电动机系统出现的混沌现象,通过微分几何理论分析及相关推导,把对非线性、强耦合的非线性系统的控制问题转变为新的线性系统的控制问题,接着根据极点配置情况对线性系统设计相应的控制输入,使系统状态快速稳定地收敛于零,有效的消除了混沌现象,理论推导及仿真结果力证了该方法的有效性。

The chaos of the permanent magnet synchronous motor system is controlled by the input-state linearization method.Through differential geometry theory analysis and related derivation,the control problem of nonlinear and strongly coupled nonlinear systems is transformed into a new linear system control problem.Then the corresponding control input of the linear system is designed according to the pole configuration.The system state rapidly and steadily converges to zero.The chaos phenomenon is effectively eliminated.The theoretical derivation and simulation results show the effectiveness of the proposed method.
