针对武装直升机载自动武器射击后坐力补偿控制过程中控制不稳定、误差高的情况,研究了武装直升机载自动武器射击后坐力补偿控制算法。依据机载自动武器射击的具体情况,结合影响武器产生后坐力的内因和外因,对其进行受力分析,同时,计算武装直升机的姿态参数,包括坐标参数和姿态角参数,在此基础上建立武装直升机的控制模型,设计相应的控制器,引入非线性干扰观测器,设计自适应控制律,实现对机载自动武器射击后坐力的补偿控制。实验结果表明:提出的武装直升机载自动武器射击后坐力补偿控制算法在实际操作上,控制延迟小,能够及时响应补偿控制变化,控制误差小,控制算法的整体容错性得到了提高。

Aiming at the situation of unstable control and high error during recoil compensation control of gunship borne automatic weapon,the recoil compensation control algorithm of gunship borne automatic weapon is proposed.According to the specific firing conditions of airborne automatic weapons,combined with the internal and external factors that affect the recoil of weapons,the force analysis is carried out.Meanwhile,the attitude parameters of gunship,including coordinate parameters and attitude Angle parameters,are calculated.On this basis,the control model of gunship is established,corresponding controller is designed,nonlinear interference observer is introduced,and adaptive control law is designed.The recoil compensation control of airborne automatic weapon is realized.The experimental results show that the proposed recoil compensation control algorithm has small control delay,can respond to compensation control changes in time,and has small control error.The overall fault tolerance of the control algorithm has been improved.
