Output Integral Sliding Mode Controllers for Acceleration of a Missile System With Parameter Perturbations

Abstract

Abstract In this paper, the guided missile system is considered as SISO plant with parameter perturbations. Standard VSC control laws fail to control the steady state error due to the structure of the system matrices. For this reason we have proposed two new robust output integral sliding mode controllers and design procedures. The total control consists of two parts: 1)equivalent control part and 2)VSC part. We have derived a new constructive sliding and stability conditions for both cases by using Lypunov's direct method. Computer simulations indicate that this approach yields a satisfactory control performance.
