Output feedback Discrete- Time Networked Sliding Mode Control

Abstract

This paper presents a Dual Rate Output feedback Discrete-Time Networked Sliding Mode Controller (DNSMC) for the networked environment. The sliding surface and the sliding mode controller are modified to take care of two major constrains i.e. network induced delay and packet loss due to introduction of network between plant and controller. The compensators are introduced to compensate both the delays concurrently, namely from sensor to controller and controller to actuator. A probability function is used to estimate the packet loss and the states are observed implicitly by measuring the output at other rate than the input. The simulation results endows the robustness under the influence of the network induced constrains.
