Abstract Model-reference adaptive controllers are popular forms of adaptive controllers which have recently found successful application in flight control systems. However, they appear to be quite sensitive to control signal saturation and may often exhibit strange behaviour even in the face of short periods of control signal saturation. It is quite difficult to directly translate constrained control strategies for linear systems to MRAC control systems, since the underlying assumption in MRAC is that “not much is known” about the plant. This talk will discuss the development of anti-windup algorithms for MRAC controllers which enable them to function satisfactorily in the presence of control constraints and, in particular, it will show how the so-called positive mu modification approach can be interpreted as an anti-windup scheme. Some limitations and extensions of the approach will also be discussed.

Biography Matthew Turner received the BEng degree in Electrical and Electronic Engineering from the University of Surrey in 1996, and the PhD degree in Control Engineering from the University of Leicester in 2000. On completion of his PhD he took up a position as a postdoctoral researcher and then was appointed to a lectureship. He is currently a professor and head of the Computational Engineering and Control Research Group at Leicester. His research interests are broadly in the areas of robust control, constrained control and absolute stability. His practical work has focused mainly on flight control applications and much of this work has been conducted with collaboration from industry. He serves as an associate editor for the International Journal of Control and has fulfilled the same role for various control conferences.
