摘要
永磁同步电动机在一定的工作条件下呈现出混沌运动状态,可能导致系统失控,使系统彻底崩溃。所以控制混沌,使系统运行到各种正常的有序状态是实际问题的需要。由于混沌系统自身的特点,使得混沌控制不同于常规控制问题,因此必须研究与其相适应的控制方案。文中基于该混沌系统的特征提出控制混沌的新方法:使混沌系统大范围渐近稳定并进行干扰抑制。采用非线性系统无源化方法设计该混沌系统的反馈镇定器,利用L2性能准则进行干扰抑制。进行计算机仿真证明该方法的有效性。
Under a certain condition, there is a chaotic phenomenon in Permanent-magnet synchronous motors, which can lead to lose control of the system and make the system completely breakdown. So it is necessary to control the chaotic system to vary order states for solving practical problem. Because the chaotic system has its particular character, the control measure is different from the other measures. So the measure must suit to its character. Based on characteristic of the chaotic system, a new measure to control this chaotic system is put forward. The measure can either ensure the global approximately stability of the chaotic system, or restrain the disturbances. And then, passivity is adopted to design feedback stabilization controller and L2-gain is adopted to restrain the disturbances. Finally, the simulation results verify the validity of the method.
