摘要: 基于伪速率调制(PRM)进行控制的闭环系统具有很强的非线性特征,稳定闭环系统由于外部干扰或参数不确定的影响在特定条件下可能出现高频自激振荡,进而频繁控制导致推进剂额外消耗.提出在线辨识自激振荡周期自动调整控制器参数的方法,当系统出现高频自激振荡时能够通过实时调整系统带宽有效消除自激振荡,并通过仿真验证了方法的有效性.

关键词: 自激振荡, 姿态控制, 伪速率调制器

Abstract: A closed loop control system based on pseudo rate modulator (PRM) may frequently oscillate due to its strongly nonlinear feature and uncertainty. And propellants exhausts extra when control system oscillates. A method is given to eliminate self excited oscillation via identifying the self excited oscillation period. The control parameters are modified according to the identification results. Finally the simulation results show that the given method is valid.

Key words: self excited oscillation, attitude control, Psudo rate modulator
