A Model-Following Technique for Insensitive Aircraft Control Systems.

Abstract

The problem of designing multivariable control systems is addressed through the use of model-following methods. A number of different model-following techniques are discussed, and their advantages and disadvantages are presented. It is shown that model-following theories can provide useful structural insight to the designer, and that they can help to integrate the methods of 'classical' and 'modern' control. A new design method is presented which, when implemented, uses model following and full-state feedback to keep the dominant roots of a system constant. Under favorable circumstances, it can do this even in the presence of arbitrarily large parameter uncertainties. The method has the attractive feature that the parameter-insensitivity and disturbance-rejection characteristics of the system can be selected independently from the no-disturbance, nominal-plant performance. Application is made to several aircraft flight control problems. (Author)
