Solutions to the Combined Sensitivity and Complementary Sensitivity Problem in Control-Systems
In a recent paper. a set of necessary and sufficient conditions for the existence of solutions to the combined sensitivity and complementary sensitivity (CSCS) problem in control systems was given, However, a practical method for constructing solutions to this problem was not presented. The computation procedure that was proposed involves constructing a sequence of rational functions to approximate an irrational function and may result in complicated high-order controllers. Ln this paper, we consider the synthesis aspect of the CSCS problem and derive an algorithm for constructing controllers that solve our CSCS problem in a simple manner, Moreover, an error in the closed-form solution of the Nevanlinna-Pick interpolation problem is revealed.
