| 英文摘要 |
| Aiming at the tracking control problem of the speed and tension system of reversible cold strip rolling mill
driven by alternating current (AC) asynchronous motors, a design method of nonsingular fast terminal sliding mode
controller is proposed based on Hamilton theory. Firstly, the initial disturbance observers are designed to observe the uncertainties
caused by parameter perturbations and load perturbation in the system. Secondly, the dissipative Hamilton model
of the outside loop of the speed tension and flux in cold strip rolling mill system is established through the pre-feedback
control, and then the dissipative Hamilton controllers are designed based on the interconnection-damping configuration and
energy shaping method. Thirdly, the nonsingular fast terminal sliding mode controllers for the current inner loop of cold
strip rolling mill system are designed based on the cascade control idea. Theoretical analysis proves that the proposed control
method can ensure the global stability of the closed-loop system. Finally, the simulation comparative study is carried
out based on the field actual data of a cold strip rolling mill system driven by AC asynchronous motors, and the simulation
results verify the effectiveness of the proposed method. |
