Abstract

It is known that the interactions between individually designed subsystems in cascaded can yield instability. To ensure the system stability, the Passivity-Based Controller (PBC) called Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) is addressed in this paper. The stability of the cascaded systems are proved via using the Hamiltonian function (storage function) as the Lyapunov candidate function. Especially the dynamic and the potential instability caused by the LC filter are regulated by rendering the LC filter into the Hamiltonian framework of the controlled subsystem. The performance of the proposed approach are illustrated in simulation and experiment.
