飞行器控制的伪线性系统方法——第二部分：方法与展望

针对第一部分提出的六类典型飞行器控制问题的共性伪线性系统模型，介绍了二阶伪线性系统的直接参数化设计方法：通过设计伪线性状态反馈控制律，可使闭环系统化为一个具有指定特征结构的二阶线性定常系统，并提供了控制系统设计中的所有自由度。另外，还以希望的闭环向量结构要求、闭环系统的干扰抑制要求和最小闭环特征值灵敏度要求为例，展示了通过综合优化设计自由度来实现控制系统的多目标设计思想。最后展望了伪线性系统理论的发展前景。

Quasi Linear System Approaches for Flight Vehicle Control ——Part 2: Methods and Prospects

For the general second-order quasi-linear system model describing the six typical flight vehicle control problems proposed in the part one of the paper, a direct parametric design approach is introduced, which designs a quasi-linear state feedback control law that makes the closed-loop system a constant second-order one with a desired closed-loop eigenstructure. Furthermore, all the design degrees of freedom are provided, which can be comprehensively optimized to realize the multi-objective designs of the system, and the design requirements on the desired eigenvector structures, disturbance attenuation and insensitive closed-loop eignenvlaues are treated as examples. Finally, the development prospect of the quasi-linear system theory is outlined.
