In this paper, we present a linear quadratic design for uncertain systems in state space representation. The parameter uncertainty is structured and value bounded. We show also that with a controller of this type, the optimality of the LQ regulator is preserved in the presence of uncertainty.

KOIVO+ + and E. B. LEE+ Summary--The problem of optimal control of a system whose mathematical model involves dependence on both a history of state type variables and the control variables is considered. The canonical equations which one obtains by application of a maximum principle for the optimal control problem are transformed into equivalent integral equations which can be solved by use of the Fredholm resoivent theory. A feedback solution is obtained.

The tracking control problem for a class of non-linear systems with control and state constraints is considered. A predictive control approach is used to derive the constrained optimal control law. The unique structure of the controller allows a parameter to be continuously tuned on-line via the sol
This paper is concerned with the design problem of non-fragile guaranteed cost controller for uncertain descriptor systems with delays. The delays are time-varying and appear in both the state and the input. The designed controller, under the possibility of feedback gain variations, can guarantee th
In this paper we investigate equivalence between control systems under timeindependent feedback transformations. We give a variation of the Pfaff theorem and use this to derive normal forms for control linear systems in \(n\) states and \(n-1\) controls under suitable regularity conditions, both in
