| 中文摘要: |
| 为解决无控刚性箭体和弹性箭体姿态控制系统的不稳定问题，以俯仰通道为例，对无控刚性箭体引入了姿态角偏差和姿态角速度偏差反馈，设计了PD控制器；对弹性箭体引入结构滤波器，进行控制器设计．仿真结果显示无控刚性箭体和弹性箭体姿态控制系统俯仰通道的稳态误差分别为0.05%、-0.30%，从而使无控刚性箭体和弹性箭体姿态控制系统的不稳定问题得到了有效控制． |
| 英文摘要: |
| In order to solve the instability of free rigid rocket and elastic rocket attitude control systems, taking the pitch channel as an example, the attitude angle and attitude angular velocity deviation feedbacks are added to the PD controller for the free rigid rocket, and a structure filter is added to the controller for the elastic rocket. The simulation results show that pitch channel steady-state errors of free rigid rocket and elastic rocket attitude control systems are 0.05%, -0.30% separately. So the instability of free rigid rocket and elastic rocket attitude control systems is controlled effectively. |
