<p>A method and a system for reducing mechanical disturbances from energy storage flywheels (32) in an electrically-powered vehicle are provided. The system includes at least two counter-rotating energy storage flywheels (32) arranged on the vehicle; vehicle dynamics, control, and sensors for sensing a disturbance to the vehicle and providing an output indicative of the disturbance. The system also provides for adjustably controlling an attitude of the vehicle in response to the output of the sensors and to counteract disturbances resulting from the at least two counter-rotating energy storage flywheels (32). A flywheel-powered electric vehicle system is also provided. The system includes an electrical power subsystem arranged on a vehicle structure; a pair of counter-rotating energy storage flywheels (32) mounted to a flywheel mounting plate, the pair of flywheels connected to the electrical power subsystem. Torque sensors are arranged between the flywheel mounting plate and the vehicle structure for sensing a net torque on the vehicle resulting from the pair of flywheels and generating a torque signal indicative thereof. A vehicle attitude sensor is arranged on the vehicle structure to produce an attitude signal. A vehicle attitude actuator and electronic processing equipment are arranged on the vehicle structure and connected to the pair of counter-rotating energy storage flywheels, the torque sensors, the vehicle attitude sensor, the vehicle attitude actuator, and the electrical power subsystem. The electronic processing equipment processes the attitude signal and the torque signal to provide a control signal to the vehicle attitude actuator for reducing the net torque on the vehicle.</p> |
