火炮直驱伺服系统的模型校正控制

射击时，火炮采用的直驱技术会对射击准确性产生较大的影响。为了削减射击力矩的影响，采用了一种火炮直驱伺服系统的模型校正控制方法。以某多管并联火炮为例计算了其单管射击力矩，建立了考虑射击力矩因素的校正控制模型，并利用 Matlab／Simulink对其进行数值仿真。仿真结果显示模型校正控制可以削弱射击力矩的影响，并且在短时间内达到稳定。该仿真结果为火炮直驱伺服系统的设计起到指导作用。

Model Correction Control for Gun Direct Drive Servo System

The shooting torque inevitably acted on the motor when the direct drive technology was used in the manufacture of a gun,which brought a negative impact on the accuracy of the design. In order to minimize the influence of the shooting torque,a model correction control method of the gun direct drive servo system was adopted. On the basis of a certain multi-tube parallel gun,its single tube shoo-ting torque was calculated;the correction control model with shooting torque factor taken into account was established and numerical simulation using Matlab/Simulink was carried out. The simulation re-sults show that the improved method can be used to weaken the influence of the shooting torque and to help the gun reach acceptable stability in a short period of time. The method and its simulation results will provide reference for the design of the Gun Direct Drive Servo System.
