“…- Compared to the results of event‐triggered control of switching systems 17‐19 that, at best, translate the observer design problem to the verification of some LMIs and the addition of complicated switching strategies, we provide a full analytic solution to the problem. Moreover, these results rely on the stringent PE condition, which is significantly relaxed here.
- We improve the results of Reference 20, that also uses DREM‐based observers, replacing the PE assumption by a very weak IE condition and achieving finite convergence time (FCT).
- Compared to the interesting results of References 22 and 24 where two complex estimators based on DREM, integral filter and resetting filtration techniques 26 were proposed to ensure global exponential estimation of unknown piecewise constant parameters, in this note we present a switched version of the LS‐DREM estimator 25 to guarantee estimation in finite time of unknown switching parameters as well as unmeasurable states.
