Control of Unmanned Sea Surface Vehicle Using Sliding Mode Controller with Saturation function for Defence Application

This paper discusses regarding sliding mode controller using saturation function in the design and development of Unmanned Sea Surface Vehicle (USSV). Mathematical model of USSV using sliding mode controller using saturation function is simulated in matlab and results are presented. It shows shortcomings in the linear control strategy such as PID and PD Control and how it can be overcome by using sliding mode with saturation function. Using sliding mode control strategy USSV can be used for autonomous operation. Simulation results of each control strategy are discussed along with conclusions.
