质量矩/直接力复合控制飞行器的姿态控制

研究了大气层内质量矩/直接力复合摔制飞行器的姿态控制问题.建立了质量矩/直接力复合控制飞行器六自由度数学模型,分析了质量矩控制和直接力控制的控制机理,基于质量矩控制与直接力控制的各自优势,提出了质量矩与直接力复合控制乜行器的姿态复合控制策略,确定了在不同条件下的具体控制方式.应用变结构理论设计了飞行器的姿态控制规律,分别给出了滑块期望位簧和发动机期望开关信息的求法,在复合控制策略的指导下,给出控制指令.仿真结果表明,方法能够在保证系统稳定的情况下有效实现飞行器的姿态控制.

Attitude Control of Mass Moment and Lateral Thrust Combined Control Fight Vehicle

A combined attitude control method is developed for the mass moment and lateral thrust flight vehicle in intra-atmospheric space.The nonlinear equations of motion which provide the basis for a detailed simulation model are derived.And then through an analysis of control principle for lateral thrust control and mass moment,a compound strategy is presented and discussed,and special control methods are given in different phases.On the basis of all above the variable structure control law is designed for mass m...
