摘要: <正>针对造纸过程中定量水分的强耦合性及时滞性等特点,利用MATLAB的仿真工具箱SIMULINK构造了典型长网纸机的多变量动态矩阵控制(DMC)算法,并进行仿真分析。通过对误差校正参数等的合理设计,采用该算法可使控制系统具有良好的稳定性、鲁棒性和抗干扰性能。

Abstract: A class of Riemann solver-free high resolution schemes with staggered grids for the compution of solutions of systems of hyperbolic conservation laws in two dimensions are presented. Because of Riemann solver-free, no complete set of eigenvectors is needed and hence weakly hyperbolic systems can be solved with much simpler programming. The nu merical results obtained under environment of MPI for parallel computation of these schemes for Euler equation and shallow water equation are satisfied.
