Reliable Guaranteed Cost Control for Linear State Delayed Systems with Adaptive Memory State Feedback Controllers
نویسندگان
چکیده
This paper deals with the problem of reliable guaranteed cost control for linear time-delay systems via state feedback against actuator faults. Based on indirect adaptive method, the proposed delay-dependent memory controller with variable gains is established, whose gains are affinely dependent on the online estimations of fault parameters. In the frameworks of linear matrix inequalities, sufficient conditions with less conservativeness than those of the traditional controller with fixed gains are derived such that the closed-loop system is asymptotically stable and the cost function value is minimized in both normal and faulty cases. Numerical examples are given to illustrate the effectiveness of the proposed method.

متن کاملAn LMI Approach to Guaranteed Cost Control for Uncertain Delay Systems
The guaranteed cost-control problem for uncertain linear systems which have delay in both state and control input is considered. Sufficient conditions for the existence of guaranteed cost controllers are given in terms of linear matrix inequality (LMI). It is shown that the state feedback controllers can be obtained by solving the LMI.

In this paper, the guaranteed cost control problem for a class of neutral delay-differential systems with a given quadratic cost functions is investigated. The problem is to design a memory state feedback controller such that the closed-loop system is asymptotically stable and the closed-loop cost function value is not more than a specified upper bound. Some criteria for the existence of such c...
