【Abstract】 A control method of variable structure based on sliding mode was proposed in order to solve the contradiction between fast response and high precision in the tension servo control system. The system was quickly reached the expected value through the continuous adjustment of the state feedback control vector. In addition,repetitive control was reduced of the periodic disturbance of winding shaft caused by uneven airbag material. Finally,the control method was simulated and analyzed. The results show that the proposed control strategy can shorten adjustment time of the system,accelerate the response speed of the system,and improve the system robustness.更多还原
