An Adaptive Cruise Control System Based on ARM CPU and PID for Agricultural Vehicles

ABSTRACT

The control system plays an important role in the agricultural vehicle guidance system. The previous guidance control system based on PI controller is the only linear, non-dynamic system, and does not work well under the complex cruising condition such as the typical nonlinear, dynamic system in the farm fields. This paper developed an Adaptive Cruise Control (ACC) system based on agricultural vehicle control system for improving its efficiency based on ARM microprocessor and PID algorithm. The real-time experiments on YTO plough tractor achieved better performance index characterizing the operation of the proposed ACC system. This work may provide a proper scheme compared with the present existing linear ACC which can be replaced by a better, nonlinear, more efficient adaptive control system.
