Coherent $H^{\infty }$ Control for a Class of Annihilation Operator Linear Quantum Systems
Aline I. Maalouf, Ian R. Petersen · IEEE Transactions on Automatic Control · 2010
This paper considers a coherent H∞control problem for a class of linear quantum systems which can be defined by complex quantum stochastic differential equations in terms of annihilation operators only. For this class of quantum systems, a solution to the H∞control problem can be obtained in terms of a pair of complex algebraic Riccati equations. In addition, the question of physical realizability of the resulting quantum controllers is related to a bounded real property.
