Mechanical Feedback

A constant tension control device of mechanical feedback is designed for the tension adjustment between the unwinding and rewinding of the flexible material, and the structure and size of the device are given. According to torque balance principle and based on purely mechanical structure, this device can control tension by adjusting the frictional force between the brake block and the unwinding wheel. The tension of controlling the unwinding and rewinding of the flexible material is analyzed, and then the control method of the tension is illustrated. Compared with the common closed loop control devices with tension feedback, the structure of the proposed device is simpler, and it has a stronger capacity of resisting disturbance in complicated electromagnetic environment.

And Control

In order to improve the characteristic and control strategy in transmission lines, a tension stringing mathematical model was established which analyzed the multiple disturbance factors of tension. According to the tension control principle of hydraulic system and the influence of different factors, a control method of constant tension adapted to the system was proposed based on pressure regulating plan. By simulation, the modified tension control system enhanced the dynamic response characteristic and stability effectively, which can realize the ideal constant tension control.

Fuzzy Adaptive

This paper proposes a fuzzy adaptive control method for uncertain horizontal platform system with unknown control gain, which is capable of guaranteeing the prescribed performance bounds. An error transformation is introduced to transform the original constrained system into an equivalent unconstrained one. Then, based on the error transformation technique and the predefined performance technique, a fuzzy adaptive controller is designed for the unconstrained system. It is shown that all the variables of the resulting closed-loop system are bounded. Finally, an illustrative example is given to demonstrate the effectiveness and usefulness of the proposed method.
