武装直升机控制增稳系统的设计

DESIGN OF THE COMMAND AND STABILITY AUGMENTATION SYSTEMS OF ARMED HELICOPTERS

用现代控制理论的方法对武装直升机进行控制增稳系统的设计。所给的状态方程为２９阶，用内部平衡系统的性质来获得一个降阶模型，用特征结构配置的方法来设计一个控制器，模态解耦是通过特征向量的选型获得的。设计的结果表明，系统得到了良好的解耦效果及闭环特性，从而提高现代攻击直升机的操纵品质。

This paper discusses design procedures for achieving a multiple input, multiple output, command and stability augmentation system for armed helicopters. It also discusses the use of balanced coordinates for obtaining a reduced order model and eigenstructure assignment techniques for designing a controller of a modern attack helicopter. Designing transient response characteristics is achieved through eigenvalue assignment and model decoupling through eigenvector shaping. Frequency and time responses are used to demonstrate the behavior of the feedback control system. Simulation shows good closed loop characteristics.
