This article intends designing and implementing a hysteresis current controller for the energy management system within an electric traction to maintain the output voltage in a certain interval whatever the disturbances to the system. The energy management system within an electric traction encompasses a battery functioning as a fuel cell within the primary energy source, an ultracapacitor considered as an auxiliary source and two direct current to direct current converters renowned as boost and buck/boost converters, whose modeling is constantly contemplated as a very difficult task. As a matter of fact, these converters are designed as switching circuits with a prevalent change of structures, which makes them strongly nonlinear. Thereby, they can be assumed as hybrid dynamical systems whose continuous parts are especially characterized by electrical magnitudes, namely, the currents and voltages in the converters, and whose discrete part is illustrated by the high-frequency switching metal–oxide–semiconductor field-effect transistor which demands faster control mechanisms to ensure proper regulation of the output voltage of two direct current to direct current converters. The validity and effectiveness strategy control of the energy management system are highlighted by numerical simulation as well as by experimental implementation on the DSPACE1104 R&D Controller Board.

电力牵引能量管理系统混合控制的设计与实现

本文旨在为电力牵引内的能量管理系统设计和实现磁滞电流控制器，无论系统受到何种干扰，都可以将输出电压保持在一定的间隔内。电力牵引系统中的能源管理系统包括一个作为主能源中燃料电池的电池、一个被认为是辅助电源的超级电容器和两个直流到直流转换器，称为升压和降压/升压转换器，其建模不断被认为是一项非常艰巨的任务。事实上，这些转换器被设计为具有普遍结构变化的开关电路，这使得它们具有很强的非线性。从而，它们可以被假设为混合动力系统，其连续部分的特征特别在于电气量级，即转换器中的电流和电压，其离散部分由高频开关金属氧化物半导体场效应晶体管说明需要更快的控制机制来确保正确调节两个直流到直流转换器的输出电压。通过数值模拟以及在 DSPACE1104 研发控制器板上的实验实现，强调了能源管理系统的有效性和有效性策略控制。其分立部分由高频开关金属氧化物半导体场效应晶体管说明，该晶体管需要更快的控制机制，以确保正确调节两个直流到直流转换器的输出电压。通过数值模拟以及在 DSPACE1104 研发控制器板上的实验实现，强调了能源管理系统的有效性和有效性策略控制。其分立部分由高频开关金属氧化物半导体场效应晶体管说明，该晶体管需要更快的控制机制以确保正确调节两个直流到直流转换器的输出电压。通过数值模拟以及在 DSPACE1104 研发控制器板上的实验实现，强调了能源管理系统的有效性和有效性策略控制。
