Abstract:
The structured singular value () synthesis technique is used to design controllers for the Active Mass Damper (AMD) Benchmark problem. The motivation for using synthesis is its ability to directly incorporate performance and robustness objectives into a multivariable control design framework. In addition to stated performance objectives, robustness of the controllers to high-frequency unmodelled dynamics (the neglected high-frequency modes of the evaluation model), modelling error in the actuator dynamics and variations in the first structural natural frequency and damping value are considered in the design. The resulting controller achieves similar performance levels on the nominal evaluation model and the evaluation model with significant variations in its first natural frequency and damping
