IMPROVING THE TILT CONTROL PERFORMANCE OF HIGH-SPEED RAILWAY VEHICLES: AN LQG APPROACH

摘要

The paper discusses on the use of an optimal LQG control design to improve the vehicle curving performance at increased running speed, employing only local (rail vehicle-based) signal measurements. It addresses the fundamental problem related with straightforward feedback control, and introduces the commercially-used command-driven with precedence scheme. A combination of simulation results and, a recently proposed, tilt control system assessment method are utilised for assessing the overall performance of the tilt controller.
