English abstract:
The chapter presents LQG and weighted H2 MIMO control design methods for the vibration control of lightweight rail car body structures. These designs are studied and compared to achieve vibration reduction and comfort improvement in a highly flexible metro rail car body. The metro car body structure is directly actuated via locally mounted Piezo stack actuators. Utilizing strain measurement signals, the control law actuates on the structure with the aim
of minimizing ride comfort-relevant acceleration signals across the car body interior. As the system is subject to variations in damping and frequency of the flexible modes, the abovementioned control methods are employed. The structure of this chapter is as follows: Firstly, an in-depth treatment of the theoretical foundations and derivations of these control design methods including an overview on relevant literature is given. Also, structure modelling and vital tools for linear dynamic system calculus are discussed. Then simulation and design models of the flexible metro car body system are presented, and the control designs are performed. Simulation results are analysed and interpreted. In an additional section, these design methodologies are applied to design real-time control laws for a laboratory scale model of a rail car body. The redesigned controllers are validated in experimental test runs and provide for extended understanding on robustness, design parameter tuning, and real-time implementation issues. Finally, conclusions are drawn from both theoretical and experimental experience, and specific properties of the design methods are discussed.
