Abstract
This paper presents an integration design and implementation of an air motor and a DC servo motor which utilizes a magnetic powder brake to integrate these two motors together. The dynamic model of the air/electric hybrid system will be derived and eventually leads to successful ECE-40 driving cycle tests with a FPGA-based speed controller. The testing results obtained by using the proposed experimental platform indicate that the total air consumption is about 256 L under air motor mode and the electric charge consumption is about 530 coulombs under DC servo motor mode. In a hybrid mode, the current reduction of the battery is about 18.5%, and then the service life of the battery can be improved. Furthermore, a prototype is built with a proportional-integral (PI) speed controller based on a field-programmable gate array (FPGA) in order to facilitate the entire analysis of the velocity switch experiment. Through the modular methodology of FPGA, the hybrid power platform can successfully operate under ECE-40 driving cycle with the PI speed controller. The experimental data shows that the chattering ranges of the air motor within ±1 km/h and ±0.2 km/h under DC servo motor drive. Therefore, the PI speed controller based on FPGA is successfully actualized.
Highlights
In Taiwan, there are more than 15 million motorcycles, mostly driven by internal combustion engines (ICEs) [1]
When the electric vehicles operate under standing start or accelerate conditions, the battery system will be operating in the large discharge region and this will shorten the service life
In the VHDL programming, the ECE-40 driving cycle is constructed by the look-up table (LUT)
Summary
In Taiwan, there are more than 15 million motorcycles, mostly driven by internal combustion engines (ICEs) [1]. Electric motors produce no exhaust emissions in their immediate environment. They suffer from the drawbacks of the battery system when used in automotive applications. When the electric vehicles operate under standing start or accelerate conditions, the battery system will be operating in the large discharge region and this will shorten the service life. As it is well known, the battery system is one of the weakest points of electric vehicles, as well as usually being the most expensive component [4]. In order to extend the service life of the battery system and reduce the cost, auxiliary power is needed to help the battery system avoid operating in the large discharge region
