A Variable Structure System (VSS) formulation and bond graph approach are used to develop a novel scheme for synthesizing reduced order models of switched systems. Switches are physical mechanisms that discontinuously redirect power, and switched systems employ switches for more efficient power conversion and/or to incorporate a control structure. A variety of power converters including electronic converters, hydraulic pumps, and clutched transmissions/differentials employ switches. It is shown how reduced order models can be derived using bond graphs and a VSS formulation to provide insight for optimizing design of switched systems. Experimental results are presented to validate this utility.
