A MODEL FOR A RIDER MOTORCYCLE SYSTEM USING FUZZY CONTROL

Abstract

A rider-motorcycle system is a representative man-machine system in view of the major role that the rider plays in determining the performance of the integrated system. The handling property of motorcycles influences safety during riding. In the study, a motorcycle model subjected to fuzzy control representing rider's perception and action is investigated to facilitate motorcycle design. A mathematical model of three-dimensional (3-D) multibody dynamics is constructed, which accounts for not only motorcycle structures but also the rider's posture change. The fuzzy controller based on control rules and fuzzy reasoning methods plays the role of the rider in a rider-motorcycle system. The fuzzy control is facilitated by the construction of look-up tables. A rider-motorcycle system undergoing circular motion is simulated. The study provides a viable means for computer-aided design of a representative man-machine control system.
