Optimal regulator, error decomposition, Youla parametrization


The sensitivity function in a generic two-degree of freedom (TDOF) control system can be decomposed into three major parts: design-, realizability- and modeling loss. The paper investigates the optimality of the realizability loss in infinite norm spaces and proposes a new iterative algorithm for the solution.
