A perspective on superaugmented flight control - Advantages and problems

摘要: Superaugmented aircraft are an important subclass of actively controlled, highly augmented aircraft. The without augmentation is unstable; the control system not only redresses stability and imbalance, but also provides effective vehicle dynamics that differ in kind from those associated with conventional In this paper, longitudinal properties unstable typical superaugmented systems used to remedy their dynamic deficiencies explored generically. topics considered include: (1) Basic flight architectures suitable reduce or completely alleviate characteristics. (2) primary characteristics regulatory systems, including governing factors linear system, dominant mode characteristics, fundamental margin properties. total available gain range factor presented as a basic measure relates degree instability, limitations, key adjustments. (3) Some flying qualities features for rate command/attitude hold, extended bandwidth, attitude command configurations.
