%X While only continuous signals are utilized in traditional system states estimation approach,information contained in discrete measurements is ignored.A new approach is proposed,that makes use of these continuous signals and also those discrete signals.In the proposed framework,information contained in these discrete events of system,denoting the changes of discrete signals,is involved in system states estimation as those continuous signals,and then the novel state estimator is constructed.Stability conditions and design procedures for this estimator are also discussed.The simulation experiment demonstrates that the proposed approach based on hybrid signals could improve the performance of system states estimations.
