| 英文摘要 |
| Based on hierarchical control structure in steady state optimization of industrial processes and iterative learning control law for linear industrial process control systems, the iterative learning control is applied to saturated nonlinear industrial control systems and nonlinear industrial control systems with changing gains, the weighted PD type closed loop iterative learning control algorithm and weighted power type open closed loop iterative learning algorithm are discussed respectively. The definitions of δ reachability of objective trajectory and ε convergence of the iterative learning control algorithm are suggested. By means of Bellman Gronwall inequality and λ norm theory, the convergence of the algorithms is also proved. The numerical simulation shows that the iterative learning control can remarkably improve the dynamic performance of industrial control systems in steady state optimizing. |
