Abstract :
This study presents an analysis about state estimation and dead-time compensation effect over constrained control systems with bounded disturbances and dead-time. It is shown that input-to-state stability and constraint satisfaction can be guaranteed by using an equivalent dead-time free system with measurable states and modified disturbances. This result may be useful to simplify synthesis and analysis of a given constrained control strategy. A linear output feedback control scheme and a tube-based model predictive control strategy are used as motivating examples.
