Description
Summary:Output feedback stabilization problem for a class of networked switched planar systems with aperiodic sampled data is investigated, and the closed-loop system is made converge to a size-adjustable set including the equilibrium. First, state feedback control laws are systematically constructed by the so-called adding a power integrator technique, a special backstepping-like method. Then, switched observers are constructed by using the aperiodic sampled data, which are sampled based on a deliberately designed event-triggered mechanism that can exclude Zeno behavior and guarantee the existence of a positive minimal inter-event time, transmitted by network and held by a zero-order holder. Combining the reconstructed state and the sampled output information, output feedback control strategy can be carried out. Simulations are provided to demonstrate the effectiveness of the proposed method.
