This paper describes the design, flight testing and accompanying analysis of two anti-windup (AW) compensators for an experimental aircraft -the German Aerospace Center's (DLR) Advanced Technologies Testing Aircraft (ATTAS). The AW compensators were designed to reduce the deleterious effects of rate-saturation of the aircraft's actuators on handling qualities. The AW compensators were flight-tested and assessed using the resulting pilot comments, in the form of handling qualities ratings (HQR's) and pilot-involved-oscillation ratings (PIOR's), and flight test data. These media demonstrate that the AW compensators improved the predictability and handling of the aircraft. The results also provide an initial understanding of the relationship between the theory and design choices for AW controllers and the response of the piloted aircraft during periods of rate saturation.
This paper develops an anti-windup scheme for systems with rate-limited actuators. The main results show how a full-order anti-windup compensator can be synthesised using an algebraic Riccati equation and several free parameters. A further result then shows how the free parameters may be chosen to influence, in an intuitive way, the local L 2 gain of the system and the size of the region of attraction. The results are of interest due to their low computational burden and hence their applicability to systems of large state dimension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
