摘要
应用自抗扰控制技术,在控制回路中增加扩张状态观测器(ESO),对飞行过程中动力系统故障等造成的干扰进行实时估计,并进行在线补偿,可显著减小发动机故障情况下的火箭姿态角偏差,提高控制品质。本方法不依赖故障诊断系统,将发动机故障视为外干扰进行在线补偿,适应性强,可靠性高,易于工程实践。
tThe active disturbance rejection control technology is used in this paper.By adding an extended state observer to control loop,the disturbance caused by the power system fault in the flight process can be estimated and compensated on-line,which can significantly reduce the rocket attitude angle deviation under the condition of engine fault and can improve the control quality.This method does not rely on the fault diagnosis system and compensates the engine fault as external disturbance,which has strong adaptability and high reliability.It is easy in engineering practice and has great application value.
