提出了蒸发流程终点浓度智能控制算法．应用启发式最优控制方法，将系统动态过程信息用节点表示，建立了启发式最优控制规则．该算法可据系统特征状态、控制效果及评价函数选择控制规则，修正控制输入．仿真实验证明，该算法有较好的适应性． An intelligent control algorithm for the concentration of the end of the evaporation process is proposed. Heuristic optimal control method is applied to express the dynamic process information of the system by node, and the heuristic optimal control rule is established. The algorithm can select the control rules according to the system characteristic state, control effect and evaluation function, and correct the control input. Simulation results show that the algorithm has better adaptability.
