Fuzzy Sliding mode Control for missile autopilot design

Abstract

In this paper, we have discussed about the Sliding mode Controller (SMC) for missile autopilot. The chattering phenomenon has been studied as the main problem of these systems; we use boundary layer method to overcome this problem. Therefore, the system is robust under various uncertainties and external disturbances. Also, the stability of the system is proved by the Lyapunov theory. In following, Fuzzy control is applied to calculate the controller gain (k), which is responsible for stability.
