Active front wheel steering system for 14 DOF armoured vehicle model due to firing force disturbance

In this paper, a study contributed in controller performance for Active Front Wheel steering System (AFWS) for armoured vehicle. A 14 DOF model of armoured vehicle is used to control the vehicle's dynamic responses especially in yaw rate, yaw angle, lateral acceleration and lateral displacement by using a simple PID controller. The responses from the vehicle model was then compared with ones from CarSim software to ensure that the model is verified. All the vehicle's parameters were extracted from High mobility Multipurpose Wheeled vehicle (HMMWV) model in CarSim. The external disturbance in this paper is the firing force that exerted on the vehicle body. By tuning the value of PID, the simulation result was obtained and analyzed.
