This paper studies the robust stability of uncertain internally delayed (i.e., in the state) systems being regulated by a sliding mode controller (SMC). A method for designing SMC is proposed. The robustness property and asymptotic stability of the system are discussed and sufficient conditions for the design of the switching hyperplane are given.
In this paper we discuss the application of H∞ Optimisation techniques to the design of a control system for a submarine. The dynamics of a submarine change significantly with speed and to cover the speed envelope from 3 to 18 knots we have developed a strategy based on switching of H∞ controllers. The necessary compensation to achieve bumpless tansfer during switching is also the basis of a controller...
Meeting required handling qualities for VSTOL aircraft using H∞, robust control design techniques is discussed. The key characteristic of VSTOL aircraft is widely varying dynamics across the flight envelope. The controller must not only have good robust stability to these changing dynamics, but also exhibit good robust performance so that handling qualities are met at all operating conditions. Here...
This paper analyzes the behavior of several control algorithm when used for a plant with saturating power-amplifiers. This analysis is mainly done by experiments using a typical DC-servo configuration. It is shown that linear feedback controllers can produce a significantly degraded closed-loop behavior in the presence of saturations of the power-amplifiers. For plants having saturated power-amplifiers...
