基于内模原理的椭圆轨道编队最优维持控制

 基于内模原理,针对椭圆轨道编队维持控制过程中存在的周期扰动问题,结合动力学方程的时变周期系数特性,设计具有干扰抑制功能的线性周期时变最优二次调节器。干扰内模的加入,使得系统响应在稳态时具有良好的控制精度,同时基于最优性原理的设计使得系统的瞬态响应过程满足某种最优性能指标要求。仿真结果表明,在椭圆轨道的编队维持控制器中引入部分干扰内模可大幅度提高维持精度。

Optimal Maintaining Control for Formation Flying in Elliptical Orbit Based on IMC Theory

There exist periodic disturbances in the process of elliptical orbit formation maintaining control.In this paper,a linear periodically-varying optimal quadratic regulator is designed by combining the internal model principle with the characteristics of periodically-varying coefficients in dynamics equations.High accuracy of control is achieved by adding the disturbance internal models to the index in the optimal control.Numerical simulations show that the proposed controller containing some disturbance inte...
