Abstract: An active control system for rolling behaviors of high-speed trains includes a sensor, a controller and an output device. The output device includes a power unit, an output unit and a casing. The power unit and the output unit are arranged inside the casing. The active control system applies active control torque to the shaking, rolling and nodding of the train body so as to control the train.

Abstract: An active rotary inertia driver system includes an output support, a drive assembly and a rotary inertia plate. The output support includes a partition plate and a housing. The partition plate is fixed on an inner wall of the housing, and the housing is connected with a controlled structure. One end of the drive assembly is fixed on the housing and connected to one end of an output shaft. The other end of the drive assembly is fixed on the partition plate. The other end of the output shaft extends out of the housing and connected to the rotary inertia plate. The rotary inertia plate is a disc or a ring with a preset mass.

Abstract: An energy-supply rotary inertia driver system for an offshore platform includes an annular fixed plate, an active control module, a wind power generation module and a solar power generation module. The system can monitor a motion state of the offshore platform in real time, and can generate a force through the active control module if necessary to apply a force torque of the offshore platform to further achieve the vibration suppression. Moreover, when the offshore platform is under normal operation, the system can act as an energy supply device via wind and solar power generation to feed electric energy to the active control module and other electrical equipment on the offshore platform when needed.

Abstract: An active composite variable damping rotational control device includes a variable damping module and a power module. The variable damping module includes a magnetorheological fluid tank and a rotational inertia wheel. The rotational inertia wheel is arranged in the magnetorheological fluid tank fully filled with magneorheological fluid. The power module includes a device tubular cavity, a driver, an encoder and a speed changer. The driver is fixed on the inner wall of the device tubular cavity. The driver, the encoder and the speed changer are coaxial. A driving shaft of the driver passes through the speed changer and extends into the magnetorheological fluid tank to be fixed perpendicularly at the center of the rotational inertia wheel. The control effect of the present invention may not be greatly affected by the change of a structural form and the change of an external load.
