Abstract

Slider vehicles apply drag-vs-energy profile guidance scheme to meet various specified constraints such as heating, acceleration and dynamic pressure. This paper first presents drag-vs-energy space state equations with some analysis. An Extended State Observer (ESO) is introduced to cope with strong nonlinear and time-varying characteristics in the guidance methodology, and the bank angle command is obtained to precisely track the drag acceleration reference based on Active Disturbance Rejection Control (ADRC). This algorithm is free of both gain-scheduling strategy and differentiation of drag acceleration. Mathematical simulation demonstrates its effectiveness.
