TRAIN BRAKING PERFORMANCE STUDIES USING SUBOPTIMAL CONTROLLERS-PART I

This report deals with the application of electropneumatic braking control strategies to a short train of three locomotives and six cars. First a general nonlinear train model is developed that allows individual braking of each member. The steady-state coupler force distribution is then derived for braking and non-braking conditions. A linearization allows the open loop system to be analyzed. Information about the train, grades and velocities is used to calculate an "off-line" schedule. Superposed to that schedule is a controller that tries to minimize the coupler force and velocity deviations from reference values. The control laws take certain input constraints into account and are derived from different system models. The controlled train is then simulated for different grades and velocity patterns. Part II of this report (CIGGT Report No. 79-12) deals with the application of the controllers developed here to a 63 vehicle train.
