| Abstract: |
| The velocity and tension system in unwinding process has the features of time-varying and strong coupling. To improve its control quality, a multivariable H-∞ control strategy was applied. The system model with structured perturbations was established, the structured singular method was used to analyze the robust stability and robust performance of the system. Simulation results showed that the controller satisfies stability and anti-interference requirements of closed loop system. |
| Key words: velocity and tension control robust control robust stability robust performance |
