CONTROL SCHEME OF VEHICULAR STRINGS

The upper controls vehicular strings and the lower controls individual vehicles. In the vehicular strings control system, the mathematical model is built as a discrete linear-state regulator problem where delay time is chosen as state variable and deviation from scheduled driving time between adjacent stations is chosen as control variable. The performance index is defined as a quadratic form concerning the delay time, the deviation from the time interval and the deviation from the driving time. It is possible to realize any vehicular string control system with various objectives by selecting the relative importance of the weighting coefficients of the first and the second terms in the performance index. The controller of the individual vehicle is called AVO (automated vehicular operation) and its two main functions are to drive a vehicle between stations in the time commanded by the vehicular string controller and to keep an accurate stoppage position at a station. The problem of controlling vehicles is modelled as a discrete linear-state regulator problem, where the deviations from both scheduled time and velocity are chosen as state variables and the deviation from any scheduled driving force is chosen as control variable. The performance index is defined as a quadratic form concerning the state variables and control variable.
