Finite-time Output Feedback Control Design for Elliptical-orbit Spacecraft Rendezvous with Sensor Delays
摘要
Abstract
This paper investigates the finite-time output feedback control design problem for space-craft elliptical orbital rendezvous systems with sensor delays.First,the true anomaly is selected as the independent variable,and a complex linear time-varying system is simplified into a linear periodic system via an invertible linear transformation.On this basis,a first-order hyperbolic partial differential equation is introduced to transform the periodic system with sensor delays into a delay-free ordinary differential equation-partial differential equation cascade system.Next,by fully exploiting the properties of solutions to the parametric Lyapunov equation,a linear time-varying observer is designed to estimate the system states.Furthermore,an observer-based periodic delayed feedback control strategy is proposed to achieve the spacecraft elliptical orbital rendezvous within a finite time.Finally,a numerical example is provided to verify the effectiveness and practicality of the proposed control design method.关键词
