| 针对重装空投过程中, 重型货物持续移动及瞬间离机严重影响载机的安全性等问题, 提出了基于线性化反馈和滑模变结构控制相结合的控制律设计方法, 利用非线性多输入多输出反馈线性化完成系统解耦线性化, 在此基础上采用滑模变结构控制设计系统内环速度与俯仰姿态跟踪控制器, 保证了系统鲁棒性, 结合外环PID高度保持控制器完成整个飞行控制系统的设计. 最后, 仿真验证了该控制器鲁棒性强, 且满足空投任务战技指标要求. |
| 英文摘要 |
| To reduce the impact on the flight safety from the translation and extraction of inner cargo in a flying aircraft, we develop a novel controller which combines feedback linearization with variable structure. The system is decoupled and linearized by using the nonlinear linearization theories of input-output feedback. On this basis, by applying the variablestructure theory, we design the inner loop for velocity control and pitch control for ensuring the system for robustness. Combining the inner loop control with the outer loop PID control for flight-altitude, we build the entire flight control system. Simulation results show that this method is feasible and useful. |
