Extended State Observer-Based Sliding-Mode Control for Three-Phase Power Converters
(IEEE, 2017-01)
This paper proposes an extended state observer (ESO) based second-order sliding-mode (SOSM) control for three-phase two-level grid-connected power converters. The proposed control technique forces the input currents to ...

Digital test design with an "ad hoc" strategy for an industrial ASIC with large dimension
(1996)
The development of digital ASIC's with a large area states a lot of doubts when the ingenieer must design a test strategy. The design of an industrial circuit advises a test to be made quite similar to the normal field ...
