| Outline of Final Research Achievements |
We tackled robust control problems for discrete-time linear stochastic systems with dynamics determined by random matrices whose uncertainties can be described with random polytopes. We successfully characterized robust stability of the systems by linear-matrix-inequality-based inequality conditions. Since the inequality conditions included expectations whose exact values are difficult to obtain, we also developed methods for robust stability analysis and controller synthesis in which the expectations are evaluated with samples of random matrices. Then, we further extended the methods so that more advanced robust control such as taking account of stability degree in the synthesis can be achieved.
