Abstract
This paper presents an algorithm to interpolate between two observer-based controllers for a linear multivariable system such that the closed loop system remains stable throughout the interpolation. The method interpolates between the inverse Lyapunov functions for the two original state feedbacks and between the Lyapunov functions for the two original observer gains to determine an intermediate observer-based controller.
