OPTIMIZATION OF THE AUTOMATIC STEERING CONTROL OF A VEHICLE IN A GUIDEWAY WITH POSITIVE MECHANICAL RETENTION
This paper addresses automatic steering with the objective of taking maximum advantage of a positive constraint guideway. Two steering approaches are examined for stability: ride qualtiy (sensitivity of acceleration at the passenger location to guidance source irregularities) and average error as it impacts on guideway width. The influence of system gain and compensation, dynamic characteristics of a wall-following suspension, and dynamics of the steering mechanism itself are examined. They are found to have an important influence on both stability and ride quality. Most of the analysis uses conventional small perturbation linear models. Transfer functions in the Laplace operator are generated to evaluate stability and the spectral densities of acceleration at the passenger location. Error is evaluated from these representations plus equilibrium determinations by using the nonlinear force relations. /Author/
