Mobile robot tracking control in a perceptive frame

Abstract

A new design method for non-time based tracking controller is presented. The key to the non-time based control method is the introduction of a suitable action or motion reference variable other than time, which is directly related to the desired and measurable system output.It enables the construction of control system with integrated planning capability, in which planning becomes real-time closed-loop process. The new design method converts a controller designed by traditional time-based approach to a non-time based controller using action reference. It significantly simplifies the design procedure. The design method is exemplified by a unmanned vehicle tracking control problem. The design procedure and simulation results demonstrate the advantages of proposed method.
