On Control Problems with Bounded State Variables

Stability and numerical solution of time variant linear systems with delay in both the state and control

In this paper, stability for uncertain time variant linear systems with time delay is studied. A new sufficient condition for delay-dependent systems is given in matrix inequality form which depends on the range of delay. Then, we introduce a new direct computational method to solve delay systems. This method consists of reducing the delay problem to a set of algebraic equations by first expand...

Linear Quadratic Optimal Control of Linear Time Invariant Systems with Delays in State, Control, and Observation Variables

The paper deals with the problem of linear quadratic optimal control associated to a coupled mathematical system wich provides a good model for an important families of linear time-invariant hereditary systems. The HUM approach based on the construction of an appropriate hilbert space and the inversion of an isomorphism is used and the optimal control is characterized by the resolution of some ...

Eigenvalue Assignment Of Discrete-Time Linear Systems With State And Input Time-Delays

Time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. The stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. It is well-known that the stabi...
