  Control of systems with operating condition-dependent dynamics, including
control moment gyroscopes, often requires operating condition-dependent
controllers to achieve high control performance. The aim of this paper is to
develop a frequency response data-driven linear parameter-varying control
design approach for single-input single-output systems, which allows improved
performance for a control moment gyroscope. A stability theory using
closed-loop frequency response function data is developed, which is
subsequently used in a synthesis procedure that guarantees local stability and
performance. Experimental results on a control moment gyroscope demonstrate the
performance improvements.
