| 中文摘要: |
| 将变质心姿态控制应用到高高空浮空器上，推导出了高高空浮空器变质心动力学模型，给出了变质心姿态运动机理。采用广义逆方法，并考虑到执行机构操纵效率约束，设计了高高空浮空器非线性复合控制器。该控制器通过执行机构权值的设置实现效率分配和故障复现，通过加权广义逆控制实现控制量的分配，从而实现控制系统重构。以某巨型柔性浮空器为例，进行了气动舵面、变质心和矢量推力共同作用的复合控制系统研究，并给出了纵向平面内轨迹高度跟踪的仿真结果。结果表明，加权广义逆方法很好地实现了复合控制的分配和重构，并给出了控制能量最小的解，提高了控制系统的操纵效率和可靠性。 |
| 英文摘要: |
| The moving mass control strategy was applied to a high altitude aerostat, and a dynamic model for its moving mass control was deduced, and correspondingly, the mass moving mechanism for the control was given. The weighted generalized inverse (WGI) method was used to design a nonlinear composite controller for the high altitude aerostat, with the actuator rate/position saturation being considered. The controller achieves actuator efficiency setting and fault recurring by choosing the weight of each implementing agency, and is able to redistribute the control variables using generalized inverse, thus achieves the control system reconfiguration. A certain composite control system combining the action of aerodynamic control surface, moving mass, and vectored thrust was studied by simulation, and the simulation result of altitude tracking was given. The simulation showed that the weight generalized inverse obtained a good distribution and reconfiguration in the composite control, and kept the minimum control energy, thereby enhancing the reliability of the control system. |
