摘要 为提高系统的稳态跟踪精度,针对一类具有范数有界不确定性的连续时间系统,提出了一种鲁棒保性能PI控制器的设计方法。结合一个二次型性能指标,采用线性矩阵不等式的方法,给出了保性能PI控制器存在的条件,并利用线性矩阵不等式的解得出了PI控制器的参数。 In order to improve tracking precision in steady state, the design method of robust guaranteed cost PI controllers for linear systems was proposed with norm-bounded parameter uncertainties and a given quadratic performance index. A sufficient condition for the existence of guaranteed cost PI controllers is derived and a procedure to determining the PI controller parameters is given in terms of the feasible solutions to a certain linear matrix inequality.
