| 摘 要： | 将最优控制与经典控制中的频域分析综合起来应用,设计了直接力/气动力复合控制自动驾驶仪.应用最优控制理论推导出自动驾驶仪的结构,并确定其增益系数,经典控制中的频域约束用于限制目标函数中的权系数矩阵的选取,以保证系统具有一定的鲁棒性.仿真结果与传统设计方法相比较,说明了应用本方法设计出的自动驾驶仪使系统响应速度更快,但超调略变大,同时系统也具有一定的鲁棒性.

| Abstract: | To design the autopilot of the missile controlled by both lateral thrust and aerodynamic force,an approach utilizing the combination of optimal control and the frequency analysis in classic control was proposed.The autopilot structure and the gain values were obtained according to optimal control,and the frequency analysis was used to determine the weighting parameters in objective function,to make sure the robustness of the system.Then the simulation results were compared with the traditional method obtain... |
