| Summary: | 碩士 === 大葉大學 === 機械與自動化工程學系 === 107 === The opjective of discuss the motorcycle braking control performance using the ABS system to control the longitudinal slip. Using the computer software as the difference between the vehicle speed and wheel speed is calculated as slip ratio, and the error reference is fed back to the PID controller for the control input signal. The ABS controller is designed for control slip ratio simulation. This research is uses the BikeSim to bulid the motorcycle typo and road typo. According to motorcycle dynamic, wheel frictional force with slip ratio, wheel force influence to design a ABS PID controller in Matlab. The differencebetween the dry road, wet road, ice road to control slip ratio simulation. And uses the slip ratio predictor to estimate the motorcycle velocity and acceleration as the control input signal. Then,the ABS PID controller is used to control the slip of different friction coefficient roads,and then the variation of the slip control curve when the locomotive is converted to the low friction coefficient road surface is discussed.
