摘要:

针对推力矢量型V/STOL飞行器起降过渡阶段动力系统转换过程存在的控制量耦合与冗余问题,设计了相应的内环增稳控制器和控制分配策略。首先,利用喷射气流效应经验公式建立了带升力损失项的动力系统与飞行动力学模型。然后,采用非线性动态逆方法设计了外环控制律,采用L1自适应控制方法设计了内环控制律,以补偿系统建模误差及参数不确定性的影响。最后,根据控制冗余度,基于效能分配准则设计了控制分配策略,实现了控制解耦,并进行了仿真验证。蒙特卡洛打靶仿真结果表明,即使存在较大参数摄动,控制器仍然可以很好地跟踪参考输入,这说明设计的控制器控制性能与鲁棒性良好。

Abstract:

To solve the problem of control quantity coupling and redundancy in the power system conversion process during the take-off and landing transition stage of the Vertical/Short Takeoff and Landing (V/STOL) aircraft, the corresponding inner loop stability augmentation controller and control allocation strategy are designed. A power system model and a dynamic model with lift loss are established by using the empirical formula of jet effect. Based on the conventional nonlinear dynamic inverse control of the outer loop, the L1 adaptive controller is designed as the inner loop stability augmentation control to compensate the mismatch and uncertainty in the system. According to control redundancy, a control allocation strategy is designed based on the efficiency allocation criterion. Control decoupling is realized, and simulation is carried out for verification. The simulation results of Monte Carlo shooting show that the controller can track the reference input well even if there is a large parameter perturbation, indicating that the controller designed in this paper has good control performance and robustness.

Key words: thrust vector, stability augmentation control, L1 adaptive control, control allocation, Monte Carlo shooting
