摘要: 研究了线性时不变广义系统的输出反馈镇定与零点配置问题。首先从状态空间角度出发,利用双互质分解方法得到输出反馈镇定控制器的参数化形式。然后从频域角度,在保证广义闭环系统容许的条件下,研究闭环系统的零点配置问题,给出了系统具有不同零点的配置方法。最后通过数值算例证明了所提方法的有效性。

Abstract: Output feedback stabilization and zero placement of the linear timeinvariant descriptor systems are investigated. First, the parametrization of the output feedback controllers by doubly coprime factorization approach is used to stabilize the descriptor systems from the statespace perspective. Then, from the angle of the frequency domain, the zero placement problems of the closedloop system are discussed in the condition that the closedloop system is admissible, and the zero placement method is proposed to design different zeros. Finally, the numerical examples are given to show the effectiveness of the method.
