In this paper, we present a tension control method for multi motor wire winding systems (MWSs). The objectives of MWS are tracking both the tension and velocity of wire. A velocity controller for rewinding motor is designed. A tension controller, whose inner loop is the velocity controller for unwinding motor, is developed. To filter out the measurement noises of velocities and estimate the load torque of motors, an augmented observer is proposed. The proposed method ensures good performance in the presence of the measurement noises of velocities noise and load torque. Simulation results validate the effectiveness of proposed method.
