Title: Power Electronic Conversion Technology for New Energy Vehicles
Abstract: Most of today’s battery-electric vehicles use battery configurations, resulting in the 150~450V DC-link voltage range, and this high voltage configuration is often called the 400V system. In contrast, in electrified truck and construction vehicles, the maximum DC-link voltage can reach 870 V, and this configuration is often called the 800V system. Currently, there are several high-end electric passenger vehicles under development utilizing the 800V system. This presentation discusses the benefits and challenges of using the 800V system in passenger vehicles. The key power electronic converters, including 800V soft switching DC-DC converter, 800V motor drive, integrated design of onboard charger and auxiliary power module, and hybrid switched-capacitor converter based power supplies, are analyzed and discussed.

Title: Advanced model predictive control of multiphase electric machines
Abstract: The multiphase machines have been widely explored in industries and academia in the past years, since they can achieve the advantages of lower power rating per phase, lower torque pulsation and better fault tolerant capability. Thus, the multiphase machines are more preferred than the three-phase counterparts in high power and safety-critical applications, such as electric ship propulsion, elevator, wind power generation and so on. In addition, the model predictive control (MPC) has emerged as a competitive technique for the control of machine drives and power electronics in recent years. There are still many challenges imposed on the MPC when it is applied in conjunction with the multiphase machines. First, in the conventional MPC, the number of prediction vectors increases exponentially as the number of phase increases. Secondly, high amount of harmonic currents is introduced due to the small leakage impedance of the winding structure of asymmetrical six-phase machines. Thirdly, the parameter mismatch will result in prediction error, thus degrading the control performance. Advanced model predictive control strategies are desired to exploit the potential of multiphase machines.

Title:Interplay between paradigms - how to select an appropriate approach for modeling biological systems
Abstract:Quantitative modeling of biological systems with Petri nets has undergone a renaissance over the past two decades. In spite of ever-growing numbers of models, it is still a question whether such models are biologically relevant. Despite the fact that most of the biological processes are mesoscopic in scale, the majority of models is based on deterministic predictions, which cannot quantify uncertainties and randomness inherent in such biological processes. Choice between deterministic, stochastic and fuzzy parameters and aspects; that is, what modeling approach to use to approximate biological systems to the desired relevance, and how to measure the parallels and discrepancies between modeling paradigms, are the main questions addressed in this work. We use Petri nets with continuous, hybrid, stochastic and fuzzy extensions to exemplify case studies. Statistical analysis reveals significant deviations between simulation results collected from three modeling approaches. Since underlying biological systems are at the mesoscopic-scale, we conclude that fuzzy stochastic approach produces quantitative results with the most biological relevance.
