The output and quality of metal plate and strip are heavily affected by performance of the main drive system of rolling mill. Aim at the characteristics of main drive system of rolling mill,such as uncertain external load disturbance and unmodelled dynamics,the model of main drive system of rolling mill is established, where uncertain external load disturbance and unmodelled dynamics are regarded as one integrated disturbance. Then, using extended states observer(ESO), a new observer is proposed to observe and compensate this integrated disturbance, and a robust controller of speed system of rolling mill is designed based on active disturbance rejection control(ADRC) technology. This controller has very strong robustness not only to external load disturbance, but also to unpredictable plant parameter variations such as inertia of load、resistance of armature. Its effectiveness is verified by the simulated result.

Aiming at the parameters of fuzzy controller and CMAC neural network are difficult to tune,GA is introduced to the control system to optimize the parameters of fuzzy CMAC neural network. The strong points of fuzzy control, CMAC, genetic algorithms and improved structure are together. A FCMAC control system is designed based on modified GA. Both the overall architecture of the system and the design of every part are proposed here. The results of simulation show that the proposed control system has better performance in the learning ability and approximation accuracy.

Motion vector field of video motion image sequences has the characteristic of center-biased and spacetime correlation. Aiming to the limitations of the existing fast block-matching motion estimation algorithms, this paper proposes a motion estimation algorithm which adaptively chooses different algorithm templates according to movement complexity and module precision. The experimental results show that the new algorithm can significantly improve the search speed of motion estimation, and saves a lot of time of motion estimation, under the premise of ensuring the quality of the reconstructed image.
