Abstract:
Pairs of counter-rotating regenerative flywheels (and ) create reinforcing torques when electrical energy is transferred between the members of a pair. The transfer of electricity can be controlled to counter undesired oscillations of a watercraft (). Motion of the watercraft () is sensed by a sensor system (), resolved into components and then the flywheels are controlled to apply torque that counteracts the undesired oscillation. Preferably, the motion of the watercraft is evaluated by the sensor in brief increments of one-tenth of a second or less.
