ON THE GENERALIZED-PROPORTIONAL-INTEGRAL MULTILEVEL SIGMA-DELTA SLIDING MODE CONTROL OF A 'BUCK' INVERTER

摘要

This article considers the output feedback controller design for a multi-level dc-to-dc "buck" power converter structure, used as an inverter, in an arbitrary bounded output voltage reference signal trajectory tracking task. The multilevel output feedback controller design is accomplished via a suitable combination of the Generalized Proportional Integral (GPI) feedback controller design technique along with a multilevel generalization of the sliding mode based Sigma-Delta (Σ - Δ) modulator. Simulations depict the feasibility of the proposed output feedback controller scheme.
