摘要： An active vibration control (AVC) system includes a shaft-driven gearbox mounted force generator (GMFG) mounted to a main rotor transmission. The GMFGs receive shaft power from an output shaft driven by the main rotor transmission and/or engine-to-transmission gearbox to avoid separate drive motors.

摘要： A system and method reduces undesired noise or vibration in a vehicle. The ambient vibration is measured and command signals are generated over time. The command signals are generated based upon the measured vibration and based upon a control weighting. By varying the control weighting over time, the maximum possible performance is always obtained subject to the saturation constraints.

摘要： A system for enhancing vibration reduction in a vehicle that utilizes one or more sensors which sense ambient vibration in the vehicle and generate a signal corresponding to the sensed vibrations. A control circuit is coupled to the sensors and receives the signals. The control circuit, utilizing Kalman filtering algorithms, generates a control signal that adapts a previous command force, from an actuator to a sensor, thereby dynamically updating a parameter that represents an estimated vehicle response. This dynamically updated parameter is a result of utilizing a covariance that is a function of an empirically derived constant value and a change in forces exerted by the actuator. The control circuit outputs this control signal to vibration generator units, which generate a vibration field for reducing vibrations in the vehicle.
