Apparatus for roll-stabilizing a vehicle broadly includes a compound physical pendulum operatively arranged to sense the lateral and angular acceleration of the vehicle attributable to an applied disturbance torque, and an inertia wheel arranged to be accelerated in the appropriate angular direction to exert a reaction torque on the vehicle to oppose the disturbance torque. The compound physical pendulum has a rigid dumbbell-shaped member mounted for frictionless pivotal movement between opposing discharge nozzles of a hydraulic amplifier. The hydraulic amplifier produces a differential control pressure in response to the acceleration forces acting on the pendulum, and this control pressure is used to operate a servovalve. The servovalve produces a drive pressure which is supplied to a hydraulic motor to accelerate the inertia wheel in the appropriate angular direction. The apparatus may further include static balance means for shifting a weight or fluid mass transversely of the vehicle to correct a static imbalance condition.
