Summary:
The l?-sensitivity of a closed-loop transfer function with respect to coefficients of a state-estimate feedback controller is analyzed, and the problem of minimizing an l? -sensitivity measure subject to l? -scaling constraints is formulated. Next, the constraint optimization problem is converted into an unconstrained optimization formulation by using linear-algebraic techniques, and an efficient quasi-Newton method is applied to solve the unconstrained optimization problem. Finally, a numerical example is presented to illustrate the utility of the proposed technique.
