15Multivariable Closed-Loop Modeling of Inverters

15.1 Introduction

In the previous chapters, closed-loop models were derived by assuming that cross-coupling transfer functions can be neglected and that inverter input dynamics depend only on the d-components [1]. This is a good trade-off between complexity of the model and its accuracy. However, the cross-coupling transfer functions may affect the dynamic behavior and stability of the inverter, for example, on impedance-based stability margins [2].

This chapter demonstrates how the closed-loop model can be formulated without the need to neglect any dynamics. The model is solved by using two-by-two transfer matrices rather than reduced-order dynamics [3,4]. The reader is urged to familiarize ...
