Abstract
In this invention there is disclosed a system and method for tuning a speed controller that is used to keep a rail-based transportation system within a prescribed speed limit while providing a smooth ride. A fuzzy logic controller is synthesized to track the performance of a train simulator to a predetermined velocity profile over a specified track profile. A genetic algorithm is used to adjust the fuzzy logic controller's performance by adjusting its parameters in a sequential order of significance.
