Improving the tilt control performance of high-speed railway vehicles: an LQG approach
Abstract
The paper discusses on the use of an optimal LQG control design toimprove the vehicle curving performance at increased running speed, employingonly local (rail vehicle-based) signal measurements. It addresses the fundamentalproblem related with straightforward feedback control, and introduces thecommercially-used command-driven with precedence scheme. A combination ofsimulation results and, a recently proposed, tilt control system assessment methodare utilised for assessing the overall performance of the tilt controller.
