This paper addresses the problem of output feedback sliding mode control of sampled-data systems. Many existing control schemes can exert high gain control efforts during transients, which can be O(1/T) where T is the sampling time period. In this paper, improved versions of the previous methods are proposed so that the control effort will be O(1). The simulation results demonstrate the efficacy of...
The problem of output feedback sliding mode control for sampled-data systems in the presence of external disturbances is considered. The proposed output feedback control strategy helps obtain a quasi sliding mode with an $O(T^{3})$ boundary layer, where $T$ is the sampling period. This outperforms the $O(T^{2})$ result induced by the one-step delayed disturbance approximation method. The proposed...
In this paper, a consensus problem for a group of n agents is considered. A switching type protocol, or law, is proposed such that the states of all the agents agree upon an average value in finite-time. Sliding mode principles have been used to achieve finite-time average consensus. Specifically the sliding surface is defined as the set corresponding to consensus, on which the sliding motion is obtained...
