中文摘要:

针对现有功率车在测试训练过程中由于踩踏速度的变化无法维持功率恒定的问题,设计了一种新型磁阻发生装置。首先,基于永磁同步电机的原理对磁阻装置基本结构进行设计,通过功率车的整体结构确定装置的基本结构尺寸,结合测试时所需的最大功率确定电磁负荷,选择永磁体,再进行定转子的结构尺寸以及绕组连接形式设计,并确定径向气隙参数,最后,分析了系统恒功率控制原理,并通过模糊 PID 控制与迭代学习控制(ILC)对系统恒功率控制效果进行了仿真与实验。结果表明,新型磁阻式功率车在踩踏速度在 60( ±10) r/ min 的范围内变化时,功率误差控制在±5 W 以内,可以接受。采用新型磁阻发生装置的功率车提高了恒功率控制效果,验证了其在维持恒功率方面的先进性。

英文摘要:

Aiming at the problem that the existing power vehicle cannot maintain constant power due to the change of pedaling rate in the test and training process, a new magnetoresistance generation device is proposed. Firstly, the magnetoresistance generation device is designed based on the principle of permanent magnet synchronous motor. The basic structural dimensions of the device are determined through the overall structure of the power car. Considering the maximum power required for the test, the electromagnetic load and select permanent magnets are determined. Then the stator and rotor structure size and winding connection form are designed, and the radial air gap parameter is specified. Finally, the system constant power control principle is analyzed. The system constant power control effect is simulated and experimented by fuzzy PID control and iterative learning control ( ILC ). The results show that the power error of the new magnetoresistive power vehicle can be controlled within ±5 W when the pedaling speed varies in the range of 60(±10) r/ min, which is acceptable. The power vehicle with the new magnetoresistance generation device improves the effect of constant power control and verifies its advancement in maintaining constant power.
