Focusing on the current issues like the complexity in design, high energy consumption, high costs etc., this article presents a project including a 2KW proton exchange membrane fuel cell control system's design and implementation which takes STM32 MCU as a core control unit. This system adopts industrial sensors to collect all varieties of parameters of the fuel cell, achieving the hydrogen supply,...
This paper presents a simplified Zero Moment Point algorithm for fall detection using inertial MEMS sensors. Based on body posture and stability judgment optimization system, we realized real-time detection and analysis of the falls. The system can be used in moving people airbag system that can prevent a major part of the induced fracture of the elderly from falls. Hardware includes the nodes that...
According to the control requirement and actual project condition of three-phase high power factor rectifier, for the sake of eliminating inconstant switching frequency in the converter that brought on rather serious power supply harmonic pollution and shock damage of power devices and reducing difficulty of filter circuit design, based on these problems the constant switching frequency control algorithm...
With the development of the Internet and the information technology, virtual laboratory may provide students and users with the vivid expression of the theory and the real performance of the physical world. Moreover, by means of the Internet, virtual lab brings the benefits of the space and time. In this paper, a virtual lab of motion control is described that a completely new system which will be...
