“…Considering small values of T in the usual discretization of the continuous-time equation (2) may lead to several numerical problems. However, when T goes to zero, matrices A σ and B σ of the δ-modulator model converge to A σ and B σ , respectively, retrieving the continuoustime model (2). Another important issue is that matrices A σ and B σ depend explicitly on the switching period T .…”

“…The literature on this power converters systems is quite rich and several control laws have been designed. One of the most popular approach relies on an average model, allowing to remove the hybrid nature of the systems and to focus on the study of a continuous-time model [2], [17], [22]. The price to pay is that the discrete behavior of the switches is lost, limiting the system performance.…”

This paper deals with the stabilization of high frequency DC-DC converters. This kind of systems can be modeled as switched affine systems subject to a periodic sampled-data control implementation. The dynamics of these systems is expressed using the δ-operator in order to cope with high frequency switching control constraints. The novelties of this paper, first, relies on the formulation of a freematrices based min-projection control law, that allows the selection of the mode to be activated, based on the knowledge of the state variables. Second, the stability theorem, expressed in terms of a tractable optimization problem, that guarantees a practical stability result to a set and delivers the optimal control law that minimizes the volume of this one. The method is then illustrated through the control of a high frequency boost converter.

“…, β N ), and, for each one of these, (28) was solved with the YALMIP+SeDuMi solver, producing a family of controllers described in (30). The final implementation of the LQR-Robust-Gain-Scheduling (LQR-R-GS) controller in the dSPACE was carried out with the help of lookup tables, used to store the family of feedback gains (30), and by interpolating them for intermediate results (see Figure 5). Albeit the lookup tables must store 110 points and perform 10 interpolations in each sampling time, the complexity of this operation is moderately low because all the tables share the same input, which enables the application of efficient prelookup techniques [48].…”

The energy storage system (ESS), as well as its efficient management, represents key factors for the success of Electric Vehicles (EVs). Due to well-known technological constraints in the ESS, there has been a growing interest in combining various types of energy sources with complementary features. Among the many possible combinations, our interest here lies in the hybridization of batteries and supercapacitors (SCs), with an active parallel arrangement, i.e., the sources are connected to the DC bus through two bidirectional DC-DC converters (step-up). Based on this ESS topology, a robust DC-Link controller is employed to regulate the DC-bus voltage and track the SCs current, in spite of uncertainties in the system. For this purpose, we start by showing that the converters uncertainty, e.g., the powertrain load, can be modelled as a convex polytope. The DC-Link controller is then posed as a robust Linear-quadratic Regulator (LQR) problem and, by exploring the convex polytope, converted in a Linear Matrix Inequalities (LMI) framework, which can be efficiently solved by numerical means. Finally, the operation envelope of the controller is extended by scheduling the gains according to energy sources voltages, an important feature to cope with the voltage variations in the SCs. To analyze the performance of the control architecture, a reduced-scale prototype was built. The experimental results show that, compared with the non-robust and non-gain-scheduled controllers, the proposed DC-Link controller offers a better transient response and robustness to disturbances. Further, the global performance of the controller is also evaluated during some driving cycles.

“…These aims are mainly accomplished through either sliding mode approach that exploits the inherent variable structure nature of the converter [7,8] or using the pulse width modulation (PWM) feedback strategies. Within the latter stream, several methods have been employed varying from linear such as the proportional and integral (PI) controller [9] and the proportional and resonant (PR) controller [10,11] to nonlinear schemes such as sliding mode controllers [12] and adaptive controllers [13].…”

The control of switched power converters has been mostly accomplished using pulse width modulation (PWM). Under this type of control, it has been shown in literature that DC-AC current mode singlephase inverter may exhibit chaotic behavior if the proportional controller of the PWM modulator is badly tuned. In this work, we present a novel method to control the inverter using an optimal control approach. Our method consists in defining the switching instances in order to achieve the reference current with minimum error. To illustrate the efficiency of our proposed method, numerical simulations and comparison with the proportional and integral controller as well as to the proportional and resonant controller are presented.
