Our objective is to develop a methodology for designing robust controllers for aircraft engines. Typically, information about engine-to-engine variations due to manufacturing tolerances and time degradation is represented by key parameters in the engine model. These parameters are statistically varied to generate a number of perturbed models from the baseline nonlinear model. This set of perturbed models into the standard norm bounded additive uncertainty form so that existing software can be used to design the controller. In the process we also propose a way of determining a nominal model which is needed in the design process. Our results show that using these modeling techniques along with modern robust design algorithms like 'my' synthesis yield controllers that deliver superior performance as compared to existing classical controllers. While these results pertain mainly to aircraft engine control, the techniques elucidated here carry over to problems where the plant to be controlled is stable and the uncertainty information is available in a similar form.
