ABSTRACT:
An active suspension for a vehicle, in particular an active tilting suspension for a railway vehicle, has a first main control loop in which a deficiency signal indicative of the difference actuator response and demand is fed through a low-pass filter to control operation of the actuator. A second control loop derives a restraining signal from actuator operation and this restraining signal is fed through a high-pass filter, which is substantially complementary to the aforesaid low-pass filter, to provide a restraining control on the actuator.
