Mixed H2 and Hinf Performance Objectives II: Optimal Control
John Doyle, Khemin Zhou, Keith Glover, and Bobby Bodenheimer
Abstract
This paper considers the analysis and synthesis of control systems
subject to two types of disturbance signals: white signals and signals
with bounded power. The resulting control problem involves minimizing
a mixed H2 and Hinf norm of the system. It is shown that the
controller shares a separation property similar to those of pure
H2 or Hinf controllers. Necessary conditions and sufficient
conditions are obtained for the existence of a solution to the mixed
problem. Explicit state-space formulas are also given for the optimal
controller
