1、引言在“具有参数补偿的线性最优化系统设计”中论论了飞行器稳定系统采用观测器获得系统状态的方法,用参数补偿原理消除弹体弹性弯曲振动,及通过反馈增益阵实现全状态最优反馈控制。本文在上述工作基础上,设计增广系统全维或降维观测器,观测包括干扰变量在内的全部状态。这样,观测器不但是状态测量装置,也是干扰的测量装置。在满足一定的条件下,设计干扰补偿通道,用干扰补偿干扰。
1. Introduction In the “linear optimization system design with parameter compensation”, a method of using observer to obtain the state of the system in the stabilization system of the aircraft is discussed. The elastic bending vibration of the projectile is eliminated by the principle of parameter compensation, and the full state is achieved by the feedback gain matrix Optimal feedback control. Based on the above work, this paper designs an augmented system full-dimensional or reduced-dimensional observer to observe all states including disturbance variables. In this way, the observer is not only a state measurement device, but also a disturbance measurement device. To meet certain conditions, design interference compensation channel, with interference compensation interference.
