“…With both the hysteresis controller and the PI controller, it is not possible to recharge the capacitor, at least not with our proposed bridge structure. After determining the superiority of the MPC for our task [36], an MPC that follows a given current profile was presented, and in [37], a similar control strategy was shown but with a bridge with the capacitor recharging structure and a new control law. In [37], no trajectory tracking was analyzed.…”

“…No stability conditions are given in the literature. The heuristic procedure to obtain the stability of the whole system, which was adopted in this paper, consists of finding the gain of the positional MPC according to relation (37) and testing the stability of the whole loop control structure. If the loop is not stable, then the value of matrix Q is reduced, and the method is repeated.…”

The paper presents a novel technique to control the current of an electromagnetic linear actuator fed by a multilevel IGBT voltage inverter with dynamic energy storage. The technique uses a "cascade model predictive control (MPC), " which consists of two MPCs. A predictive control of the trajectory position predicts the optimal current, which is considered to be the desired current for the second MPC controller in which a hysteresis control technique is also integrated. Energy is stored in a capacitor using energy recovery. The current MPC can handle a capacitor voltage higher than the source voltage to guarantee high dynamic current and disturbance compensation. The main contribution of this paper is the design of an optimal control structure that guarantees a capacitor recharge. In this context, the approach is quite new and can represent a general emerging approach allowing to reduce the complexity of the new generation of inverters and, in the meantime, to guarantee precision and acceptable switching frequency. The proposed technique shows very promising results through simulations with real actuator data in an innovative transportation technology.

“…Thus, variable opening strokes, which have recently proven to be efficient for engine operation, are hardly possible. For this reason, our attention at the beginning was focused on linear motors as valve actuators in order to be able to control the motion across the complete range, including positioning the valve at every specified stroke [8], [9]. In [2] a combination of a linear motor and a reluctance motor was presented.…”

Camless internal combustion engines offer improvements over traditional engines in terms of torque performance, reduction of emissions, reduction of pumping losses and fuel economy. Theoretically, electromagnetic valve actuators offer the highest potentials for improving efficiency due to their control flexibility. For real applications, however, the valve actuators developed so far suffer from high power consumption and other control problems. One key point for the control is the design of the reference trajectory to be tracked by the closed loop controller. In this paper an optimal trajectory design technique aimed at minimizing power consumption is proposed. An optimization problem that explicitly considers the physical constraints of the system is formulated and a suboptimal solution is derived by exploiting local flatness of the system

Double Stage Double Output DC–DC Converters for High Voltage Loads in Fuel Cell Vehicles

This article aims to enhance the output voltage magnitude of fuel cells (FCs), since the actual generation is low. The traditional technique is too complicated and has a cascaded or parallel connection solution to achieve high voltage for multiple loads in vehicles. In this case, electronic power converters are a viable solution with compact size and cost. Hence, double or multiple output DC-DC converters with high voltage step up are required to feed multiple high voltage loads at the same time. In this article, novel double stage double output (DSDO) DC-DC converters are formulated to feed multiple high voltage loads of FC vehicular system. Four DSDO DC-DC converters called DSDO L-L, DSDO L-2L, DSDO L-2LC, and DSDO L-2LC are developed in this research work and all the converters are derived based on the arrangement of different reactive networks. The primary power circuitry, conceptual operation, and output voltage gain derivation are given in detail with valid proof. The proposed converters are compared with possible parallel combinations of conventional converters and recently available configuration. Comprehensive numerical simulation and experimental prototype results show that our theoretical predictions are valid and that the configuration is applicable for real time application in FC technologies for 'more-electric vehicles'.Energies 2019, 12, 3681 2 of 19 elements [17,18]. Further, for implementation, they need complex control logic and increased driver modules to protect and control the semiconductor devices. Quadratic boost converters achieve a high voltage conversion ratio, but high current/voltage rating components/devices and the internal resistance of the inductors limits the output voltage [19]. Multistage diode/capacitor-based DC-DC converters have been proposed to achieve high voltage gain [20][21][22][23][24]. However, multiple discharging/charging loops of the capacitors lead to increased conduction loss, cost, and size, and reduced efficiency due to their parasitic nature. Converters have been proposed to get multiple outputs from a single input source by using push-pull, half-bridge, full-bridge, and fly-back converter topologies [25][26][27]. In all cases, high voltage is obtained with a high transformer rating on the primary side. Therefore, these converters cannot provide a proper solution for low weight/cost applications.The parallel configurations of traditional converters such as boost, buck-boost, Cuk, single ended primary inductance converter (SEPIC), and ZETA can be possible solutions to achieve multiple outputs. The power circuitry of possible configurations without common front-end structure are shown in Figure 1a-e. These configurations provide two outputs using two different control switches. However, the voltage gain is not significantly improved, even when using a large number of components and devices. Furthermore, in order to reduce the component or device counts, common front-end structure can be a solution, as shown in Figure 1f-j. These configurations provide dual output...
