摘要
针对垂直/短距起降飞机在悬停段存在的动力学耦合、推力矢量控制冗余以及易受风干扰的问题,提出了一种基于增量非线性动态逆的协调解耦控制方法。首先,根据垂直/短距起降飞机概念方案,建立了推力矢量模型和悬停段的飞机六自由度非线性模型。然后,根据时标分离原则,对不同时间尺度的子系统使用增量非线性动态逆方法设计了控制律。对于推力矢量控制冗余,采用改进的自适应粒子群算法进行控制分配。仿真结果验证了方法的有效性,以及对飞机参数摄动和风干扰的鲁棒性。
To deal with the issue of dynamic coupling, thrust vector control redundancy and vulnerability to wind for vertical and/or short take-off and landing(V/STOL) aircraft in hover mode, a coordinated decoupling control method based on incremental nonlinear dynamic inverse(INDI) was proposed. Firstly, according to the V/STOL aircraft concept scheme, the thrust vector model and the hover six degrees of freedom nonlinear model were established. Then, according to the principle of time scale separation, INDI method was used to design control laws for subsystems with different time scales. For the thrust vector control redundancy, an improved adaptive particle swarm optimization(PSO) was used to allocate the control. Simulation results show that the proposed method is effective and robust to aircraft parameter perturbation and gust disturbance.
