Partial Integrated Guidance and Control Design for Hypersonic Vehicle in Dive Phase

Abstract

Abstract. Considering the potential unstable problem using Euler angle, the quaternion is used to take its place in proposed method. What is more, A partial integrated guidance control (PIGC) model is derived based on six-degree-freedom model to solve the guidance and control problems of hypersonic vehicle in dive phase, the desired body rates is calculated in the outer loop as virtual control signals by making use of the information of the state of vehicle and the relative motion between vehicle and target, and the fin deflection signals is obtained in inner loop by using the sliding mode controller to track the body rate commands. And the results of the simulation demonstrate the effectiveness of the proposed method.
