摘要
针对航空制导炸弹的滚转通道,提出了利用自抗扰控制进行滚动控制设计的新方法。通过降阶扩张观测器对系统的扰动实时估计并实时补偿,使被控制对象被"线性化"成"积分串联型"系统,针对该系统仅仅需要PD控制。仿真结果表明,该控制器比PID具有较强抗干扰能力及较高的控制品质。
Based on guided bomb control system, an active disturbances rejection control （ ADRC ） is designed to ensure the high precision and high reliability in the case of the internal dynamics and external dis- turbance. A linear extended state observer （LESO） is proposed for on-line estimating and compensating the total dynamics, then the plant dynamics is reduced to a group of integrators by applying ESO and the PD controller is only used. The simulation results show that the control system designed has more excellent char- acteristics than PID controller.
