Lateral Acceleration Control Design of a Non-Linear Homing Missile

Abstract

Input-output approximate linearisation of a non-linear fourth order system has been studied. A method for controlling the non-linear system that is i/o linearisable is examined that retains the order of the system in the linearisation process, hence producing a linearised system with no internal or zero dynamics. Desired tracking performance for lateral acceleration of the missile is achieved. Simulation results are shown that exercise the final design and show that the linearisation and controller design are satisfactory.
