Modern control theory has for a long time been largely the domain of mathematicians and control theoreticians. Engineering applications were rare and partial, for a part due to the inaccessability of the theory to the practical engineer, but mainly because of the lack of computing power available to process the estimation and control algorithms resulting from the theory. In the course of the sixties and especially in the seventies the digital computer made enormous advances resulting in a reduction in size, power and cost by several magnitudes. Moreover, successful attempts were made to develop efficient algorithms which could be implemented in moderate-size onboard computers. As a result of these developments, realisation of the potential benefits of modern control has come within grasp and several applications in the aerospace field can be witnessed to-day. The present Agardograph is an attempt to present a picture of the advances in modern control as applied to aerospace system design. The Agardograph is divided into three parts. Part one deals with some basic concepts of control theory, part two contains a number of chapters on practical design techniques developed from the theory, and finally part three describes a number of design examples and practical applications in real systems.
