Modeling and control of constant tension system

In order to eliminate the interference of the load, constant tension system with the motor and the spring is established. By parameter identification of the motor, the model of the motor is obtained and the model of the system is established. According to the characteristics of the constant system, the correction controller and the H
_∞
controller are designed. Through the xPC-Target experiment, the two methods are proved that they have good effects to suppress disturbance of the load.
