(DC) network subject to (i) unknown ZIP-loads, ie, nonlinear loads with the parallel
combination of constant impedance (Z), current (I) and power (P) components, and (ii)
unknown time-varying disturbances. Using the port-Hamiltonian framework, two
decentralized passivity-based control schemes are designed. It is shown that, using the
proposed controllers, the desired equilibrium is exponentially stable and local input-to-state …
