针对参数具有确定性及不确定性的连续系统,给出两种严格耗散PI控制器的设计方法.首先,系统参数确定时,采用线性矩阵不等式方法,导出了类状态反馈和静态输出反馈严格耗散PI控制器存在的充要条件,并由线性矩阵不等式的可行解构造出严格耗散PI控制器增益的显式表达式;然后,考虑系数矩阵均具有范数有界不确定性时的鲁棒严格耗散控制问题,得到相似的结果;最后,通过数值算例表明了所给方法的有效性. For the continuous system with deterministic and uncertain parameters, two kinds of design methods of strictly dissipative PI controller are given.Firstly, when the system parameters are determined, linear state matrix inequality method is adopted to derive class state feedback and static output feedback strictly The necessary and sufficient conditions of the dissipative PI controller are given, and the explicit expression of the strictly dissipated PI controller gain is constructed from the feasible solutions of the linear matrix inequalities. Then, considering the existence of norm-bounded uncertainties of the coefficient matrix Robust and strictly dissipative control problems, and get similar results. Finally, numerical examples show the effectiveness of the proposed method.
