[CT Rotation Motion Control System].

The paper introduces a new design of the CT rotation motion control system. The system is controlled by a variable frequency drive as a controller and a general induction motor as an actuator. In addition, this paper also introduced the model selection of CT rotating control device and the parameters setup for variable frequency drive. Meanwhile, a test method of the rotor position servo control system is also introduced at the end of the paper. The new system has lowcost, high-performance features, fully meets the requirement of CT rotation motion control.
