For the rolling system, it should be a multi-variable, strong disturbance and coupled nonlinear system. As the precondition of ensuring the precision of strip thickness, it is necessary to ensure that the system is robust. The controller should be able to suppress the disturbance of the system and remain the system stable under the uncertain parameters. Taking into account the complexity of the system,...
Given that the LQG benchmark is closer to the actual production, performance assessment of cascade control system based on LQG benchmark has been proposed. The joint input and output subspace identification algorithm was used to estimate the process model, noise transfer function, the inner loop controller and the outer loop controller. And three possible cases could be considered to evaluate cascade...
In the industrial process, not only is the output of the system expected to achieve the minimum variance, but also the variance of process input fluctuates in a certain range. However, minimum variance benchmark can meet the former but not the requirements of latter because of strong control effect. Therefore, subspace identification with combined input and output is utilized in this paper to identify...
Computer simulation technology, which with application of software platforms likes FLASH, MultiSim and MATLAB/SIMULINK, was introduced into teaching progress, considering the existing teaching situation and features of the motion control system. By combining the theory explaining and simulation results together, it become more easy to reveal and exposit the essence of the lecture, more specific and...
According to the phenomenon of width losing in slab end, the spread of slab end including edger pressing, dog bone spread and nature spread, short stroke control was used in 2300 hot strip roughing mill. The parabola model has been proposed in this article, because of the disadvantage of broken line used by 2300 hot strip mill, and the online implementation plan of parabola model has been given. The...
