摘要
该文考虑一个线性系统满足多频段不同设计指标的控制问题,改进已有的GKYP引理,提出分频段控制思想,将控制综合指标FDI（频率不等式）表示形式转化为LMI线性矩阵不等式形式,设计有限频段的动态输出反馈控制器。通过对柴油发动机转速控制器的仿真验证了这一思路的可行性。
In this paper, the control system is considered in three different frequency domains. According to the method used in papers [4], the new method, dynamic output feedback synthesis based on piecewise frequency design method is proposed. In particular, the controller is designed under the sensitivity specifications for three frequency ranges （low, middle, high frequency） without weighting functions, such that the resulting closed-loop systems are asymptotically stable. Finally, design examples for a diesel generator set speed control system are given to prove the feasibility of the proposed method.
