Stochastic output feedback controller design for two tank nonlinear interacting system

Abstract

In this paper, stochastic output feedback controller is designed for two tank interacting nonlinear multi input multi output (MIMO) system. It is assumed that the control loop is closed over a communication network in which sensor data and the control signal are communicated via the same communication network. Packet delay and dropout are the main disadvantage of a communication network. The goal is to obtain a stochastic output feedback controller that counteracts the effect of packet delay and dropout. A necessary condition is given for the closed loop stability of two tank interacting system in terms of linear matrix inequalities (LMI). The controller gain is then calculated by solving the LMI. The servo and regulatory performance of the designed controller are validated in simulation platform.
