Abstract
In this paper, we extend the state feedback results of Prieur et al. (NOLCOS 2010) to the linear output feedback case, when the plant state is not available and is estimated via a Luenberger observer. Two techniques, based on different reset maps and flow and jump sets and guaranteeing global practical asymptotic stability of the origin of the closed-loop system, are proposed. The effectiveness of the solutions is illustrated on a simulation example where we show suitable reduction of the output overshoot.

Abstract
In this paper, we extend some results of Prieur et al. (NOLCOS 2010) by adding a dwell- time logic. The idea is to augment a pre-existing (not necessarily stabilizing) continuous-time controller by resetting its state in suitable regions when flow conditions, based on suitable Lyapunov-like functions and a dwell-time logic, are not satisfied. The additional flexibility due to the dwell time allows us to establish global exponential stability of the origin and guarantees some robustness properties. Moreover the solutions of the corresponding hybrid closed-loop systems can be made arbitrarily close to the ones in Prieur et al. (NOLCOS 2010) and therefore the optimal techniques for the maximization of the decay rate or for the overshoot reduction hold.

Abstract
This paper deals with the global asymptotic stabilization problem for a class of bilinear systems. A state feedback controller solving this problem is obtained uniting a local controller, having an interesting behavior in a neighborhood of the origin and a constant controller valid outside this neighborhood. The approach developed is based on the use of a hybrid loop, and more precisely a hybrid state feedback. This result is extended to the case where the state of the plant is not fully available and only the measured output can be used for control purposes. In this case, a dynamical controller constituted by an observer and a state feedback is built by means of hybrid output feedback framework. In both cases, the conditions are expressed by a set of linear matrix inequalities.
