摘　　要：针对两套舵机差动控制的单兵火箭弹,提出了基于BTT控制原理的自抗扰控制器。对于俯仰通道,建立三通道二阶非线性耦合模型,采用自抗扰控制器,实现俯仰通道的解耦控制;对于滚转通道,考虑对偏航通道的耦合影响,建立独立的自抗扰控制器,以满足滚转和偏航通道的性能要求。数字仿真结果证明设计的自抗扰控制器可以满足单兵火箭弹的控制要求,具有优良的跟踪精度、鲁棒性以及对非线性强耦合系统的解耦性能。Aiming at two sets of individual rocket rockets with differential control of servos,an auto-disturbance-rejection controller based on the BTT control principle was proposed;For the pitch channel,a three-channel second-order nonlinear coupling model was established,and the ADRC controller was used to realize the decoupling control of the pitch channel;For the rolling channel,considering the coupling effect on the yaw channel,an independent ADRC controller was established to meet performance requirements for roll and yaw channels;The digital simulation results show that the designed ADRC controller can meet the control requirements of individual rockets,with excellent tracking accuracy,robustness and decoupling performance for nonlinear strongly coupled systems.
