摘要
In this paper, a PID controller for a special road-rail vehicle is developed. The dynamic model is derived to properly consider the vehicle and track vibrations. This model contains the effects of track elasticity which makes it more reliable and precious compared to traditional models. The vehicle model contains a two dimensional 10 DOF vehicle model, and the track model consists of 40 sleepers. In addition, the effect of the sleeper number on car-body vibration is investigated. The results show that the present vehicle-track coupled model is more efficient in controller design compared to traditional ones. Finally, tuning of controller gains is performed with the aid of a genetic algorithm, in order to achieve a well-organized active suspension.
