| Abstract: | Complex dynamics characters of rolling mills system are studied.The dynamical equation and the state equation of rolling mills system are established.By the phase portrait and Poincaré map,the chaos forming process of the system is studied under the presented system parameters.The chaos controlling methods by the addition of constant motivation and the addition of periodic motivation are dissertated and analyzed numerically by the numerical solution.The chaos of the system is controlled by the three methods. The allowable range controlling variables and the steady orbit of the system under controlling are obtained. |
