Abstract
Control by Interconnection (CbI) and Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) are two nonlinear design methodologies that exploit passivity to construct stabilising controllers. While CbI is known to be a subset of IDA-PBC, the converse link has remained open. This paper revisits CbI by utilising dynamic invariants beyond Casimirs and a more general control structure. Using this more general structure we show a one-to-one correspondence between IDA-PBC and CbI controllers for the class of mechanical systems without friction.
