Fuzzy-adaptive control method for off-road vehicle guidance system

Navigation decision-making for off-road vehicle is very important in precision agriculture. Since the operating environment of the agricultural vehicles have the diversity and complexity, it is necessary for the navigation decision-making method to have self-adaptability and robustness. Simulation can make accurate predictions for the dynamic behavior of the vehicle, and provide analytical basis for the design of vehicle navigation systems. In this study, a new type of three-dimensional vehicle guidance simulation system was developed and a vehicle model was created based on MRDS. The fuzzy-adaptive control method was designed to solve the problem of overshoot. The results of simulation and real navigation experiment showed that the developed system could achieve the simulation of vehicle navigation and control successfully and provide the help to the design of the real navigation systems, and the designed fuzzy-adaptive control method could effectively weaken the control process overshoot.
