调节L2增益抑制耦合发电机组的混沌现象
Chaos suppression in the coupled dynamo-system by adjusting the L-two-gain
【摘要】 耦合发电机系统在一定条件下出现混沌,它可能导致系统失控,使系统彻底崩溃.当系统存在不确定因素干扰时,提出了L2性能准则控制方法:使耦合发电机系统渐近稳定和进行干扰抑制.然后采用非线性系统无源化方法设计混沌系统的反馈控制律,利用L2增益进行干扰抑制.最后计算机仿真证明该方法的有效性.
【Abstract】 Under certain conditions, chaos may occur in a coupled dynamo-system, which can cause the system to be out of control or completely to breakdown. To deal with the uncertain disturbances in the system, we put forward the L-two-gain control scheme to asymptotically stabilize the chaotic system and restrain the disturbance. The passivity method is then applied to design the feedback stability controller, and the L-two-gain is adjusted to restrain the disturbance. The simulation results demonstrate the validity of the method.
