Relay control systems are widely employed in a variety of technological domains because they are simpler and, in many cases, have better dynamic properties than other types of control system. The aim of this book is to present a theory of relay control systems that is based on the concepts of transfer functions and frequency and time characteristics. While giving an account of the general properties of relay control systems, the author devotes ample space to the analysis and computation of concrete examples. Although the reader is assumed to be acquainted with Fourier series and operational calculus, the appendices contain some background mathematics to make the book as self-contained as possible.

The frequency characteristics and statistical properties of the buffet loads measured on the unswept wing and tail of a fighter airplane have been studied in the stall and in the shock regime. The results indicate that the wing loads in buffeting can be treated as the Gaussian response of a simple elastic system. The tail loads appear to represent a more complicated pattern.
