基于AMESim/Matlab抑制悬停武装直升机射击扰动

Inhibiting Firing Disturbance for Hovering Helicopter Gunship Based on AMESim/Matlab

武装直升机武器机炮系统在进行射击时会产生巨大连续不规则的后坐能量,使直升机的飞行姿态发生明显变化,进而影响了射击精度;当直升机处于悬停姿态时,这种扰动的影响更加明显。为了消除射击扰动的影响,对炮塔液压伺服控制系统进行了分析和建模,依据合理的控制理论设计相应的PID控制器,并且利用AMESim/Matlab对整个系统进行联合仿真。结果表明,所设计的控制器能够有效地抑制射击扰动。

Helicopter cannon weapon system firing can produce huge irregular continuous recoil energy, so that the helicopter in flight change significantly, which affects shooting accuracy. When the helicopter is in hovering attitude, this disturbance is more significant. To eliminate the impact of fire disturbance, analysis and modeling for the turret hydraulic servo control system were made. According to rational control theory, the PID controller was designed. AMESim/Matlab integrated simulation of the whole system was completed. The simulation results verify that the designed controller can effectively suppress fire disturbance.
