Description
Summary:The paper deals with the tilt control performance of high speed railway vehicles. In particular it discusses the integration of active tilt control with an active lateral secondary suspension solution using LQG control design. The tuning of the weighting matrices of the LQG controller, for the aforementioned dual-actuator system, is accomplished using Genetic Algorithms based upon minimizing given tilting performance metrics. Issues of vehicle modeling and practical tilting performance are also included. The solution is validated via appropriate simulations and comparison with a conventional (tilt-only) precedence controller which provides a performance benchmark for the local control strategies
