“…Then a feedback controller (FBC) for each loop is designed by using the characteristic ratio assignment (CRA) method. [11,12] It is well known that using only feedback control cannot provide predictive control that can compensate for the effects of known or measurable disturbances. Therefore, we introduce a feedforwad compensator to improve the vehicle's tracking performance near curves.…”

This paper presents automatic guidance control of a single-articulated all-wheel-steered vehicle being developed by the Korea Railroad Research Institute. The vehicle has an independent drive motor on each wheel except for the front axle. The guidance controller is designed so that the vehicle follows the given reference path within permissible lateral deviations. We use a three-input/three-output linearised model derived from the nonlinear dynamic model of the vehicle. For the purpose of simplifying the controller and making it tunable, we consider a decentralised control configuration. We first design a second-order decoupling compensator for the two-input/two-output system that is strongly coupled and then design a first-order controller for each decoupled feedback loop by using the characteristic ratio assignment method. The simulation results for the nonlinear dynamic model indicate that the proposed control configuration successfully achieves the design objectives.

“…Recently, new control design methods have been introduced for PID and first-order controllers [4][5][6]. Unlike typical optimization procedures that seek a single "best" solution, these methods seek to find the entire set of solutions meeting or exceeding a given set of specifications, such as gain and phase margins, H ∞ margins, desired overshoot and settling time.…”

-In this paper, we present some remarks on the correlations between  and  domains when a discrete-time transfer function is converted from -plane by using the -transform. With time response specifications, when a digital filter or controller is designed in -plane, the -transform is useful for the purpose if only the -transformed system closely approximates to the continuous-time system. It will be shown that the approximation is accomplished only in the specific region depending on sampling time. Also, it is noted that such an approximation should be carefully dealt with for the case where a discrete-time reference transfer function is synthesized for the use of direct digital design.
