PARAMETER-DEPENDENT REDUCED-ORDER H{sub}∞ CONTROLLER USING A LOOP-SHAPING APPROACH. A SOLUTION TO THE EDF BENCHMARK PROBLEM

摘要

Solutions to a benchmark problem using H{sub}∞ optimization are presented. Loop-shaping ideas are first applied to define the H{sub}∞ criterion. Two approaches are then investigated to produce reduced-order controllers, namely, full-orderH{sub}∞ optimization followed by model reduction, and reduced-order H{sub}∞ optimization in the LMI framework. Results obtained using both approaches are compared.
