Adaptive Switched Linear Systems with Average Dwell Time to Compensate External Disturbances
Given a linear switched system composed of both Hurtwiz stable and unstable subsystems, and with additive unknown constant disturbance, a switching law with average dwell time between Hurwitz stable and unstable subsystems is proposed, together with an adaptive algorithm to compensate the unknown additive disturbance. Using Lyapunov theory, exponential stability of a desired degree of the plant...
متن کاملGraph-Based Minimum Dwell Time and Average Dwell Time Computations for Discrete-Time Switched Linear Systems
Discrete-time switched linear systems where switchings are governed by a digraph are considered. The minimum (or average) dwell time that guarantees the asymptotic stability can be computed by calculating the maximum cycle ratio (or maximum cycle mean) of a doubly weighted digraph where weights depend on the eigenvalues and eigenvectors of subsystem matrices. The graph-based method is applied t...
متن کاملPiecewise Lyapunov Functions for Switched Systems with Average Dwell Time
The stability properties of linear switched systems consisting of both Hurwitz stable and unstable subsystems are investigated by using piecewise Lyapunov functions incorporated with an average dwell time approach. It is shown that if the average dwell time is chosen sufficiently large and the total activation time ratio between Hurwitz stable and unstable subsystems is not smaller than a speci...
متن کاملStability of Switched Systems with Average Dwell-Time
It is shown that switching among stable linear systems results in a stable system provided that switching is “slow-on-the-average.” In particular, it is proved that exponential stability is achieved when the number of switches in any finite interval grows linearly with the length of the interval, and the growth rate is sufficiently small. Moreover, the exponential stability is uniform over all ...
متن کاملμ-Dependent model reduction for uncertain discrete-time switched linear systems with average dwell time
In this paper, the model reduction problem for a class of discrete-time polytopic uncertain switched linear systems with average dwell time switching is investigated. The stability criterion for general discretetime switched systems is rst explored, and a -dependent approach is then introduced for the considered systems to the model reduction solution. A reduced-order model is constructed and ...
