Lire la suite >The problem of designing an observer capable of reconstructing the continuous and discrete states for a class of switched linear systems is addressed. A stack of dynamical observers based on the super twisting algorithm with finite and uniform-in-the-initial-condition convergence is considered, which provides an estimate of the continuous state and, at the same time, produces residual signals suitable for reconstructing the discrete state. An appropriate ‘projection’ of the residuals is suggested, which allows to speed up the reconstruction of the discrete state. Formal ‘distinguishability’ conditions guaranteeing that the discrete state can be uniquely reconstructed are derived. Lyapunov-based proofs of convergence, and numerical simulations, support the proposed approach.Lire moins >
