Abstract (en)
[origin: EP0713817A1] A control system wherein an electronic control unit (14) generates a drive signal for a hydraulic device (13l, 13r, 15) for rotating the body (11) of a railroad car (3) about a longitudinal axis (G) of the car to reduce the non-compensated transverse acceleration to which the passengers are subjected. The control system presents a differentiating circuit (37) and a proportional circuit (31), which are supplied with an error signal ( theta e) equal to the difference between a reference signal ( theta c) and a feedback signal ( theta z) indicating the actual tilt angle of the body. The outputs of the differentiating circuit (37) and the proportional circuit (31) are added to generate a drive signal for driving the hydraulic device (13l, 13r, 15); and the differentiating circuit (37) presents a derivative gain (Gd) which is a function of the derivative in time (d¦ theta e¦/dt) of the error signal ( theta e) modulus. <IMAGE> <IMAGE>
