“…In addition, more advanced algorithm can be considered, like the predictive algorithm presented in paragraph 1.3 (and in [1]), involving three different measurements, and including the processing time in its definition. Other algorithms, like sliding mode control ( [2]), capacitor charge balance ( [3]) or additional feed-forward ( [4]) could also be considered. In the end, the easy tuning of the algorithm parameters as well as the possibility of using more evolved algorithms are strong assets of the "digital world".…”

The present document aims to show the advantages of a digital implementation of the regulation(s) used for the control of DC/DC converters. In a first step, a general overview of the capabilities provided by digital solution, w.r.t. analogue, will be introduced. An example of a pure digital algorithm (the predictive programmed current control) will also be presented. In a second step, a practical application of a digital control will be considered. In this example, the output voltage of two Buck DC/DCs, connected in parallel, is controlled via a digital regulation. This application also integrates different possible features (soft start, current sharing, embedded scope…), easy to implement in digital, and whose analogue equivalent would be hard or impossible to obtain. Finally, a quick overview of the radiation-hardened ASIC developed by Thales Alenia Space will be given. This component, called "Digital Programmable Controller" (DPC) is totally suitable to implement digital regulations for space applications.

This paper presents a novel digital controller for the high-switching-frequency buck converter based on the principle of predictive control. Compared with a traditional current-mode predictive controller, the prediction of the inductor current and the output voltage are performed at the same time by adding a control variable to the DPWM signal that can dynamically adjust the time of voltage jump. It accelerates the convergence rate during transient states, while inherently preserving the rejection of power and reference perturbations. The analysis of controller's operation illustrates the dual-state-variable predictive attributes that lead to the digital implementation. To further enhance the power efficiency of the controller, an 1-1 MASH 6-1 DPWM with a feasible dither generation module is proposed to restrain the idletone effects without deteriorating the closed-loop stability as well as to preserve reasonable cost in silicon area. Experimental results verify closed-loop operations at switching frequency up to 4 MHz only limited by the discrete buck converter. The converter is well regulated over a large output range with excellent dynamic performances.Index Terms-DC-DC converter, digital control, digital pulse-width modulator (DPWM), predictive control, switchedmode power supply.

Abstract-This paper investigates the robust sliding mode control (SMC) problem for a class of uncertain nonlinear stochastic systems with mixed time-delays. Both the sector-like nonlinearities and the norm-bounded uncertainties enter into the system in randomly ways, and such randomly occurring uncertainties (ROUs) and randomly occurring nonlinearities (RONs) obey certain mutually uncorrelated Bernoulli distributed white noise sequences. The mixed time-delays consist of both the discrete and the distributed delays. The time-varying delays are allowed in state. By employing the idea of delay-fractioning and constructing a new Lyapunov-Krasovskii functional, sufficient conditions are established to ensure the stability of the system dynamics in the specified sliding surface by solving certain semidefinite programming problem. A full-state feedback SMC law is designed to guarantee the reaching condition. A simulation example is given to demonstrate the effectiveness of the proposed SMC scheme.
