摘　　要：针对传统全闭环炮控伺服系统因运动耦合难以实现快速、精确调炮问题,分析耦合产生原因,提出全闭环炮控伺服串级控制技术。将运动耦合视为对两个伺服控制通道的速度扰动,利用捷联惯导所测量的空间角速率作为反馈构成空间角速率环以控制调炮速率,抑制扰动影响。通过理论分析和仿真验证,其结果表明,全闭环炮控伺服串级控制技术能够有效地抑制扰动影响,使得伺服系统能够在较短的时间内达到系统所要求的稳态精度。It was difficult to adjust cannon rapidly and accurately in traditional all closed-loop gun control servo system because of the motional coupling. For this problem, the causes of the motional coupling were analyzed and the all closed-loop gun control servo cascade control technology was put forward. To control the adjust cannon angular rate and inhibit rate disturbance, motional coupling was regarded as the speed disturbance of the two servo control channels and the strapdown inertial navigation measured spatial angular rate was used as feedback to constitute spatial angular rate closed-loop. Through the theoretical analysis and simulation verification, the results show that all the closed-loop servo cascade control technology can effectively restrain the disturbance, and the servo system can achieve the cannon adiustin~ precision that the system required in a short time.
