摘要
研究飞行器大角度姿态机动状态反馈保性能控制器设计问题。采用修正的Rodrigues参数建立了飞行器姿态控制运动模型,将非线性的飞行器姿态系统模型转化为线性参数可变模型(LPV模型)。将平方和优化技术和Lyapunov理论相结合,给出了飞行器大角度姿态机动保性能控制器设计方法。仿真结果表明了所提方法的有效性。
The problem of state feedback guaranteed controller design for large angle attitude maneuver was investigated. By using modified Rodrigues parameters, the attitude dynamics of the spacecraft was represented in terms of linear parameter varying （LPV） systems. The state feedback guaranteed cost controller design approach was proposed by combining Lyapunov theory and sum of squares （SOS） optimization. Simulation results demonstrate the effectiveness of the proposed design approach.
