Model-free norm-based fixed structure controller synthesis den Hamer, A.J.; Weiland, S.; Steinbuch, M. Abstract-This paper presents a method to perform modelfree fixed structure controller synthesis. Based on frequency response data of the plant, the parameters of a predefined controller structure are optimized directly with respect to closedloop performance specifications. As a result, no parametric plant model is required such that time consuming iterative identification-synthesis procedures

Furthermore, based upon these results, a cost-function is formulated that can be exploited to converge from a destabilizing-to the stabilizing controller parameter region. Both the stability guarantee and performance optimization procedures are combined in one optimization algorithm that is illustrated by means of an example.
