摘　　要：电动自行车一直以来存在行驶里程短的问题,而且在市区行驶条件下,存在频繁启停过程。以电动自行车再生制动系统为研究对象,建立由无刷直流电机、结构可变的双向Buck-Boost型DC-DC变换器、超级电容器和控制器构成的混合储能电动自行车再生制动系统数学模型,并应用再生制动模拟试验系统对其进行计算和验证,结果表明所建立的数学模型准确有效。为了在制动过程中保持较小的制动转矩波动范围,采用恒流控制策略来控制电枢电流。仿真结果和实验数据表明,研究的混合储能系统可有效吸收再生制动能量,通过采用恒流控制策略,可实现稳定的制动转矩,并在制动过程中达到较高的能量回收效率。Electric bicycles always have the problem of short driving mileage,and there are frequent start-stop processes under urban driving conditions.Taking regenerative braking system of electric bicycle as the research object,this paper establishes a mathematical model of regenerative braking system of hybrid energy storage electric bicycle,which is composed of brushless DC motor,bidirectional Buck-Boost DC-DC converter with variable structure,super capacitor and controller,and calculates and verifies it by using regenerative braking simulation test system.The results show that the mathematical model is accurate and effective.In order to maintain a small range of braking torque fluctuation during braking,a constant current control strategy is adopted to control armature current.The simulation results and experimental data show that the hybrid energy storage system studied in this paper can effectively absorb regenerative braking energy.By adopting constant current control strategy,stable braking torque can be achieved and high energy recovery efficiency can be achieved in the braking process.
