Abstract
Abstract
In view of the high power current source inverter (CSI) switching frequency is limited and system load parameter is variable, system output performance is affected. An interconnection and damping assignment of passivity-based control (IDA-PBC) for three-phase CSI is proposed. The lumped-parameter model of three-phase CSI with independent storage unit is established, and its port-controlled Hamilton (PCH) model in Park coordinate is proposed. The control rate of the closed-loop system is obtained by solving the parametric partial differential equation based on interconnection and damping assignment. The controller is designed, and the system stability is analysed by Lyapunov function. The Simulation and experiment results show that the inverter can output a good sinusoidal voltage, which has strong anti-interference ability to the load disturbance. The stability and robustness of the system are also improved.
