Abstract :
In this paper, an application of robust stability analysis tools for uncertain systems is presented. It is shown that these analysis techniques can provide an alternative method to the now well-established H∞ approach, in providing a simpler analytical insight into the problem in hand. A study of part of the control system for the Rolls-Royce Pegasus aeroengine at various operating conditions is presented, and it is shown how these tools can assist in improving the robust stability and performance of the engine
