Abstract :
The purpose of railroad vehicle active suspension is to attenuate low frequency vibration caused by resonance of passive suspensions equipped between a car body and trucks. We have considered the above purpose as loop shaping problem in control design, and have applied H ∞ control theory to solve this problem. Main point is to introduce a weight function which has the maximum gain near the resonance frequency. Also we discuss the performances of the proposed H ∞ control with running test by the experimental vehicle
