Since the late 1980s, Netherlands Railways (NS) have been developing a new train (SM90) for stopping services. In this paper, the controlled pneumatic swing-plug door is discussed. With the SM90 concept, a microprocessor controlled door system is chosen, instead of the previously used purely pneumatic system. A theoretical, non-linear, dynamic model is developed for the SM90 door system. The non-linearities are due to the door kinematics and pneumatics. Simulation results compared with real measurements show a close resemblance. This makes the model suitable to analyse the controlled door system behaviour and to test new door kinematic parameters, without the help of costly experiments. In order to develop in some sense an optimized controller, the non-linear model is linearized. The linearized model shows two weakly damped and one slightly instable pole, which vary with the chosen operation point. Using this linearized model, the influence of the different parameters (such as inertias and door kinematics and the design parameters of the torque cylinder) on the dynamic behaviour of the door can be investigated.
