【 摘 要 】

The paper focuses on robust state estimation and control for nonlinear system with uncertain parameters. In particular, the problem is oriented towards a practical application for a laboratory three-tank system. The proposed approach starts with a general description of the system and assumptions regarding uncertain parameters and a nonlinear function. The subsequent part of the paper is concerned with the design of the robust observer and controller for nonlinear systems. To confirm the performance of the proposed approaches, the final part presents results obtained for the laboratory three-tank system.
