| 摘 要： | 针对一类具有范数有界不确定性的广义系统，当系统状态不可测时，提出了一种基于输出反馈的鲁棒预测控制器综合算法．采用ＬＭＩ方法以及变量变换思想，将无限时域“最小最大”优化问题转化为线性规划问题．确定出一组分段连续的输出反馈控制序列，给出了输出反馈控制律存在的充分条件，证明了优化问题在初始时刻的可行解可以保证广义闭环系统是渐近稳定且正则无脉冲的．仿真实例验证了所提出方法的有效性．

| Abstract: | The problem of robust output feedback model predictive control is studied for the singular systems with norm-bounded uncertainties when the states of controlled systems are unmeasurable.Based on the idea of variable transformation and LMI methods,the infinite time domain "min-max" optimization problems are converted into linear programming problems.A piecewise continuous output feedback control law is obtained and the sufficient conditions for the existence of this control law are given.It is proved that th... |
