摘要
火箭炮在发射状态时存在燃气流冲击力矩等强干扰,使得发射后炮管偏离初始位置,故提出基于复瞄的火箭炮伺服系统控制。以火箭炮伺服系统为对象,建立系统数学模型,在此基础上运用自抗扰理论设计了非线性扩张状态观测器及相应的控制律,来减弱燃气流等强扰动对系统发射精度的影响,提高火箭炮的复瞄速度与精度。数字仿真结果显示,系统具有良好的跟踪性能,并且在燃气流冲击等干扰下能够很快返回初始位置,证明了该方法的有效性。
In response to the existing strong disturbance of gas flow in the state of launch for the rocket launcher,which makes the gun tube deviate from the initial position after launching,the rocket servo system based on reaim is put forward.The system mathematical model is established based on rocket servo system,and then through the use of the theory of ADRC,nonlinear extended state observer and the corresponding control law are designed so as to weaken the impact of strong disturbance on the system firing accuracy and improve the speed and precision of reaim of the rocket launcher.Digital simulation results show that the system has a good tracking performance,and that under the disturbance of gas flow,the system can quickly return to the initial position,with the effectiveness of the proposed method proved.
