IDA-Passivity-Based Control for Boost Converter with LC Filter Supplying Constant Power Load

An interconnection and damping assignment (IDA) passivity-based control (PBC) scheme for boost converter cascaded with LC filter supplying constant power load (CPL) is presented in this paper. The plant is described by port-controlled Hamiltonian (PCH) form. To perfect the implementation of the CPL application, an improved IDA-PBC is introduced based on the error between the desired equilibrium point and the state variable. Furthermore, the virtual damping assignment technique is addressed to tune the dynamic characteristic and an adaptive interconnection matrix is introduced for building the internal links in PCH models. Simulation and experimental results are given to show the effectiveness of the proposed approach.
