TRAIN BRAKING PERFORMANCE STUDIES USING SUBOPTIMAL CONTROLLERS-PART II

This report deals with the application of controllers (described in CIGGT Report No. 79-11, "Train Braking Performance Studies Using Suboptimal Controllers - Part I) to a 63-vehicle train containing three locomotives evenly spaced along the train. An additional controller derived from a modified long train model is also included. The behaviour of different electropneumatic braking strategies is studied in simulation. The purpose of the controllers is to minimize coupler forces and velocity deviations from reference values due to grades and other disturbances. An off-line schedule and switching policies that take into account the braking constraints are applied; both features were developed in Part I. An eigenvalue analysis of all the different piecewise linear closed loop systems is also given, allowing an estimate of performance improvements from pole shifting properties. Open and related problems are listed for further research.
