Abstract :
This paper is concerned with stability and control problems of systems with delayed states or delayed inputs respectively. Delay-dependent results for the two problems are derived using an integral quadratic constraint approach. For the stability problem, we consider systems with two independent state delays. For the control problem, we deal with systems with delayed state and delayed input. Conditions are provided to find the upper bounds for the delays in both cases and the controller gain matrix for the control problem using linear matrix inequality (LMI) technique. An application to a continuous stirred tank reactor is also addressed.
