Abstract

This paper deals with the problem of determining anoptimal controller which minimises thenorm of a given aircraftwhile guaranteeing that an upper limit of its norm is not exceeded. Theproblem is tackled by means of a linear matrixinequality formulation, which allows one toconstrain the eigenvalues of the model to within afixed region of the complex plane. Key features ofthe method are the possibility of simultaneously

  • 1. keeping the maximum value of the inputdemand under control

  • 2. taking flying quality requirements intoaccount

  • 3. assuring a minimum level of systemrobustness against uncertainties of the model.

The approach is simple to handle and is well suited tothe design of aircraft stability augmentationsystems. A discussion of two case studiesdemonstrates the effectiveness of the procedure.
