<p>A vibration controller for a vehicle, which incorporates cylinders (4A), (4B) for suppressing the vertical vibration of an automotive body (1) and a cylinder (4C) for suppressing the lateral vibration provided in parallel with springs (3A), (3B) for supporting the body (1). Detection signals from vibration acceleration detectors (5A), (5B) and (5C) are compensated by compensating circuits (6A), (6B) and (6C), respectively, and further amplified through amplifiers (7A), (7B) and (7C), respectively, and applied to servo valves (8A), (8B) and (8C), respectively, which control the internal pressures of the cylinders (4A), (4B) and (4C), respectively. Since the compensating circuits (6A), (6B) and (6C) are so adapted that their transfer functions form the product of an integrating element, a primary leading element and primary lagging element, there is no peak over a wide frequency range in the response of the vibration acceleration of the body (1). </p> |
