Improved Adaptive Hamiltonian Control Law for Constant Power Load Stability Issue in DC Microgrid: Case Study for Multiphase Interleaved Fuel Cell Boost Converter

“…For other solution Cespedes et al [13] studied passive damping techniques using a supplementary LC filte Conversely, many active damping techniques have been studied to regulate the networ the "virtual inductor technique" proposed by Liu et al [14]; the "virtual resisto approach" studied by You et al [15]; and the "virtual impedance approach" proposed b Lu et al [16]. Among these nonlinear control schemes, the interconnection and dampin assignment passivity-based control (IDA-PBC, or the Hamiltonian Lyapunov control) ha also received attention in the last decade to address the CPL instability issue [17,18]. Th As presented in [8], the dynamic behavior of CPLs is comparable to incremental negative impedance, which, under certain conditions, can introduce large oscillations or dangerous instability in the DC distribution.…”

“…Conversely, many active damping techniques have been studied to regulate the network: the "virtual inductor technique" proposed by Liu et al [14]; the "virtual resistor approach" studied by You et al [15]; and the "virtual impedance approach" proposed by Lu et al [16]. Among these nonlinear control schemes, the interconnection and damping assignment passivity-based control (IDA-PBC, or the Hamiltonian Lyapunov control) has also received attention in the last decade to address the CPL instability issue [17,18]. This Hamiltonian energy control law is clear-cut, has high dynamics, and is sufficiently effective.…”
