LONGITUDINAL CONTROL IN GUIDED TRANSPORTATION SCHEMES USING THE MOVING-CELL PHILOSOPHY

The longitudinal control of vehicles in automated transportation systems using the moving-cell approach is considered. A linear, sampled-data controller has been derived which has been shown to yield good vehicle response characteristics; the responses being optimal with respect to a defined quadratic performance index. An extended system model has been proposed which considers the problem of inaccessible state variables and which attempts to deal with the effects of random disturbances and measurement noise. The resulting optimum controller and linear state estimator have been shown to be extremely effective at maintaining the vehicle at or near to its desired position, and at smoothing out fluctuations in the rate of change of propulsive force, despite very noisy measurements and large input disturbances.
