| Abstract: |
In this invention there is disclosed a system and method for generating a fuel-optimal reference velocity profile for a rail-based transportation handling controller. The fuel-optimal reference velocity profile is used to reduce the amount of fuel consumption. The fuel-optimal reference velocity profile is generated to take into account the speed that a train must travel at in order to satisfy a given schedule, speed constraints that will minimize fuel consumption, and recommended speeds that will prevent train breaks, derailments, cargo damage and violation of safety rules. In this invention, the fuel-optimal reference velocity profile is generated by using a genetic algorithm.

What is claimed is:
1. A system for generating an optimized velocity profile in a rail-based transportation handling controller, comprising:
- a train simulator for simulating an operation of a rail-based transportation system over a specified track profile;
- a velocity profile generator for generating a velocity profile for operating the rail-based transportation system over the specified track profile;
- a fuzzy logic controller for controlling the operation of the train simulator in accordance with the velocity profile provided by the velocity profile generator, the fuzzy logic controller tracking error and change in error between the train simulator operation and the velocity profile and providing a control action to the train simulator that minimizes the error; and
- a velocity profile optimizer, coupled to the train simulator and the velocity profile generator, for optimizing the generated velocity profile in accordance with the operation of the train simulator, wherein the velocity profile optimizer comprises at least one fitness function.
