碩士 === 國立中正大學 === 機械工程學系暨研究所 === 101 === Nowadays, the electric bike is getting more and more popular in modern society. It becomes basic needs for people who live in either suburbs or urban cities using in a variety of environments and purposes. This thesis develops an embedded system for the electric bike with capability of dynamically varying the transient for driving the motor. The system includes a DSP (digital signal processor) to process the transfer function for calculating the output current for the motor. A dynamic parameter setup approach, LPV (linear parameter varying), is used in this system to set up the transfer function. By adjusting the specific transfer function parameters with a physical knob, the system is able to change the curve of output currents for the motor, hence making the electric bike adjustable and suitable for variable usage. The system is implemented and tested on a physical electric bike, and the experiment results show that the system works properly and effectively.
