Smooth Tilting Motion Control of a Train Using Two Hydraulic Actuators

초록

Hydraulic actuation systems for tilting trains are usually composed of independent actuators in order to escape from position errors due to bulk modulus of the hydraulic systems. For a hydraulic control system using two independent cylinders, this paper presents the modeling of the hydraulic actuation system, control logic, and simulation results of the hydraulic control system. Simulation results for position responses of two cylinders using position commands calculated from tilting angles show the validity of the proposed hydraulic two-actuator system.
