摘　　要：针对一类磁悬浮列车半转向架结构系统的分散输出反馈抗干扰控制问题,通过适当的坐标变换将磁悬浮列车半转向架结构系统的输出跟踪控制问题转化为2个子系统的分散输出反馈抗干扰控制问题,并利用广义比例积分状态观测器技术,分别为2个子系统设计扰动观测器来估计系统测量的状态和干扰;利用扰动观测器的输出信息和输出反馈占优技术为各个子系统设计分散输出反馈抗干扰控制器.理论分析结果表明,在所给出的分散输出反馈抗干扰控制器下,整个闭环系统的状态将收敛到可调的任意小的区域内.仿真结果验证了所给控制算法的有效性.For a class of maglev train semi-bogie structure system,through the appropriate coordinate transformation,the system output tracking control problem is transformed into two subsystems of decentralized output feedback anti-disturbance control problem.it used the generalized proportional integral state observer technique to design a disturbance observers for two subsystems to estimate the states and disturbances measured by the system.At the same time,a decentralized output feedback anti-disturbance controller is designed for each subsystem by using the output information of disturbance observer and the dominant technique of output feedback.The theoretical analysis results show that the state of the whole closed-loop system will converge to an arbitrarily small adjustable region under the given decentralized output feedback anti-disturbance controller.The simulation results show the effectiveness of the proposed control algorithm.
