The invention discloses a controller-based active radial bogie and an active steering control method thereof. The controller-based active radial bogie comprises an active radial bogie body, a drivingcircuit, a displacement sensor and the controller; the active radial bogie body comprises a main framework, an auxiliary framework and a radial driving mechanism; the main framework is hinged to the auxiliary framework; the two ends of the radial driving mechanism are connected with a front rotating arm and a rear rotating arm of the main framework respectively; the displacement sensor is installed on the main framework; the displacement sensor and an pulse encoder are connected with the controller; the controller is connected with a motor of the radial driving mechanism through the driving circuit. With the controller-based active radial bogie and the active steering control method thereof, the active steering control effect of the active radial bogie can be improved; the running stability and curve trafficability of a railway vehicle are improved; control is stable; steering control precision is high; immunity to external interference is almost realized; accurate active steering is achieved; the abrasion of wheel sets is effectively reduced; and the service lives of the wheel sets are prolonged.
