Paper Title
Sliding Sector Controller for Missile Autopilot Design

Abstract
The paper introduces a design method for sliding sector controller for a class of nonlinear systems. For this purpose, nonlinear sliding surfaces are formed from the solutions of the so-called State-Dependent Riccati Equation (SDRE) based sliding sector controller (SSC) method. Therefore, nonlinear sliding sectors are built which are the sectors covering the nonlinear sliding surfaces. The SSC is designed such that the nonlinear system states are forced to inside the sliding sector and track the desired states. The method is illustrated by applying it to a nonlinear missile model in order to design an acceleration autopilot.
