The invention belongs to the technical field of helicopter vibration active control, and particularly relates to a dual-motor control method for an actuator of a helicopter vibration active control system. The helicopter vibration active control system actuator is an eccentric wheel type actuator and comprises eccentric wheels, brushless direct current motors, a motor controller, a gear transmission assembly and a cartridge receiver assembly. The brushless direct current motors comprise the first brushless direct current motor and the second brushless direct current motor which correspond to the two sets of eccentric wheels respectively, and the brushless direct current motors are used for controlling the phases of the eccentric wheels and the rotating speed of the motors. According to the method, the two eccentric wheels are respectively driven through the two brushless DC motors. The double brushless direct current motors are controlled in a mode of combining a master-slave control technology and a coordination control technology, master-slave control is adopted in an initial force building stage, coordination control is adopted in a new operation response instruction, and the output force precision and the response speed of the actuator are effectively improved.
