| 摘要: |
| 针对三种不同结构的过载自动驾驶仪进行了对比研究，推导了驾驶仪控制回路的闭环传递函数，并对闭环稳态误差进行了分析。基于极点配置方法，设计了自动驾驶仪控制参数。在此基础上，研究了各驾驶仪控制回路对执行机构动力学延迟、非线性环节以及测量噪声的响应特性，并进行了对比分析，为飞行器过载自动驾驶仪的选型和设计提供了依据。 |

| Abstract: |
| Three different types of acceleration autopilot have been analyzed in detail.Based on the closed loop transfer function derivation，the steady state errors of each control loop have been compared.The gains of the autopilot were derived through pole assignment method.Step responses of three autopilots with dynamic delay，non linear element，and measurement noise have been evaluated.The comparative study provides the basis for acceleration autopilot design and selection. |
