The invention belongs to the technical field of helicopter model rotor tests, and particularly relates to a real-time automatic adjusting system and method for a rotor cone of a rotor model test bed. The system is composed of a vibration sensor, a cone sensor, an electric variable-pitch pull rod and a controller, the vibration sensor and a cone measuring sensor are installed on a rotor wing test bed, and in the cone adjusting process, the controller randomly commands the electric variable-pitch pull rod to act to obtain a vibration signal of the rotor wing test bed and a rotor wing cone signal; training and learning an electric variable-pitch pull rod control system to generate a rotor cone control law, and then calculating the actuation length of each pull rod through a controller by combining the control law with a vibration signal and a rotor cone signal so as to automatically adjust the rotor cone in real time. 本发明属直升机模型旋翼试验技术领域，具体涉及旋翼模型试验台旋翼锥体实时自动调整系统及调整方法。系统由振动传感器、锥体传感器、电动变距拉杆以及控制器组成，在旋翼试验台上安装振动传感器和锥体测量
