“…The aircraft demonstrated advanced fighter technologies that have been used in the development of many modern high performance military aircraft. A linear model was obtained by trimming the aircraft at 25000 feet altitude and 0.9 Mach speed (Cifdaloz et al, 2003). This linear model is a MIMO model having an unstable phugoid mode.…”

“…Furthermore, using the noted Qparametrization (or Youla parametrization), the performance indices are convex with respect to the free parameter Q. Examples of flight control design using convex optimization include Cifdaloz et al (2003), Puyou et al (2004) and Ferreres and Puyou (2006). The convex combination method was proposed by Liu and Mills (1998a), (see also Liu and Mills, 1998b).…”

Aircraft flight control systems often require the satisfaction of multiple simultaneous specifications to fulfil different robust stability and performance objectives along with good handling qualities. Many specifications such as H ∞-norm, overshoot, undershoot, etc are convex with respect to the closed loop transfer matrix. In this paper it is suggested to use the convex combination method to integrate H ∞ frequency domain specifications with additional time domain constraints. For this purpose, existing techniques are used to design an H ∞ controller which is then modified in a new structure using Qparametrization which makes the problem convex in the new design parameter Q. At this stage, if different controllers are obtained for each convex specification, they can be combined into a single controller using convex combination which could satisfy all specifications.

Control theory deals with disciplines and methods leading to an automatic decision process in order to improve the performance of a control system. The evolution of control engineering is closely related to the evolution of the technology of sensors and actuators, and to the theoretical controller design methods and numerical techniques to be applied in real time computing. New control disciplines, new development in the technologies will fertilize quite new control application fields. Based on the contributions of the Technical Committees within CC2 the status report gives an overview of the current key problems in control theory and design, evaluates the recent major accomplishments and forecasts some new areas. It points out some control fields, which could be challenges for future research.
