Abstract :
This paper examines the gain-scheduling problem with a particular focus on controller interpolation with guaranteed nonlinear stability. For linear parameter varying model representations, a method of interpolating between controllers utilizing the Youla parameterization is proposed. Quadratic stability despite fast scheduling is guaranteed by construction, while the characteristics of individual controllers designed a priori are recovered at the design points.
