Active Steering Control of Railway Vehicles using Linear Quadratic Gaussian (LQG)

초록

In urban transit systems, railway vehicles are often required to negotiate tight curves. During curve negotiation, the wheelsets of conventional vehicles generally misalign radically with the track increasing wheel/rail contact forces and resulting in increased wheel and rail wear, outbreak of squeal noise, fuel consumption, and risk of derailment. This paper presents active steering controller design in the railway systems using Linear Quadratic Gaussian. Simulation results have been shown that the proposed LQG method methodology robustly yields uniform performance with adequate response over the axle weight and wheel conicity variation range.
