Interconnection and Damping Passivity-Based Control applied to a single-phase voltage source inverter

In this paper, a control expression for a single-phase inverter following the Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) methodology is developed; this is achieved in a stationary framework using the single-phase d-q transformation. The proposed controller is designed exploiting the passivity properties of the averaged model of the circuit, while its evaluation is carried out in an experimental setting to examine its robustness properties with respect to load uncertainty and dynamic transient response. Both linear and nonlinear loads are considered in the experiments. The proposed controller is compared with another passive control expression obtained with the standard PBC approach under the same experimental operation.
