Observer-based control for a class of hybrid linear and nonlinear systems

“…In this paper, we address the control of a class of hybrid systems with switching linear dynamic equations depending on a discrete state, called mode, which is not fully accessible. For such systems, a novel observer-based control scheme is presented that is based a Luenberger observer and a mode predictor to estimate the continuous and discrete states, respectively, There exist many systems that result from the combination of smooth continuous dynamics and sudden switches (see, among others, [5,13,9,17,18]). Switching is modelled by means of hybrid automata with a discrete state that usually represents a specific operation mode of the plant.…”

“…In the worst case, we have q 3 LMIs, but such a number can be reduced in general. If the instantaneous value of the switching mode is known in real time, we have to satisfy (9) with i = j, and hence to deal with q 2 LMIs. Moreover, we may account for the knowledge of the switching rule F to set the mappingF in such a way to reduce the number of constraints on the overall.…”
