给出了广义线性磁悬浮对象的数学模型,分析得出其具有非渐进稳定的特性.在此基础上,通过系统变换方法,得到了一种利于设计H∞控制器的结构,并且将参数不确定性问题化为H∞控制的标准形式,给出了采用输出反馈的H∞控制综合方法.通过一个仿真的例子,说明该控制算法具有良好的稳定性、快速性以及精确度.通过这种方法,可以有效地对一般的磁悬浮对象进行控制
The mathematical model of generalized linear magnetic levitation object is given, and its characteristics of non-asymptotic stability are obtained. Based on the above, a structure that is beneficial to the design of H∞ controller is obtained by the system transformation method. The problem of sexuality is the standard form of H∞control, and the H∞control integrated method using output feedback is given.An example of simulation shows that the proposed control algorithm has good stability, quickness and precision.Through this method, , You can effectively control the general object of magnetic levitation
