Robust output feedback stabilizability via controller switching
Savkin AV., Skafidas E., Evans RJ.
The paper considers the output feedback robust stabilizability problem for uncertain dynamical systems. The uncertain system under consideration is a composite of a continuous-time plant and a switched controller. A necessary and sufficient condition of absolute stabilizability is given in terms of the existense of suitable solutions to a dynamic programming equation and a Riccati algebraic equation of the H∞ filtering type. A real time implementable method for robust stabilization is also presented. © 1999 Elsevier Science Ltd. All rights reserved.
