14th IFAC Symposium on Control in Transportation Systems (CTS) -- MAY 18-20, 2016 -- Istanbul, TURKEY, WOS: 000381502600046, The railway transportation has a significant impact on both the freight and passenger carriage, therefore it should provide a comfortable, safe, fast and inexpensive riding. In this paper, a six-degree-of-freedom half-car model for a typical high speed passenger vehicle is derived to study the ride motions of the vehicle under the random rail inputs. The random rail excitation is considered as an output of a second-order linear filter to white noise excitation and the temporal correlation between the front and the rear wheels is predicted by a second-order Pade filter. The unified "track-vehicle-human" model is formulated and an active suspension based on a Linear-Quadratic-Gaussian (LQG) control is designed to minimize the performance index which is a weighted sum of vehicle performance measures such as carbody vertical and pitch accelerations, front and rear suspension strokes, rail holding and control forces, Int Federat Automat Control, Tech Comm Transportat Syst TC 7 4, Int Federat Automat Control, Tech Comm 7 1 Automot Control, Int Federat Automat Control, Tech Comm 7 2 Marine Syst, Int Federat Automat Control, Tech Comm 7 3 Aerosp, Int Federat Automat Control, Tech Comm 7 5 Intelligent Autonomous Vehicles
