Reduced-order multi-objective ℋ∞ control of an overhead crane test setup

A novel convex approach for reduced-order multi-objective controller synthesis is presented, and experimentally validated on an overhead crane test setup. For this setup, a discrete-time linear time-invariant model is identified. Starting from a full-order controller for the identified model, reducedorder multi-objective ℋ_∞ controllers are designed by successively solving convex optimization problems. Experimental validation results on the test setup sustain the practical potential of the proposed controller design approach.
