Uncertainties and, in particular, large inlet distortions, affect closed-loop stability, performance, and erode surge margins of aircraft gas turbine engines. Traditional robust control techniques can be combined with robust reference governors to preserve the stability and tracking performance, while enforcing the surge margin constraints. The paper(More)
In this paper, we consider a class of optimization problems having the following characteristics: there exists a fixed number k (1≤k<n) which does not depend on the size n of the problem such that if we randomly change the value of k variables, it has the ability to find a new solution that is better than the current one, we call it O k. We build a new set(More)
