摘要
本文以非稳定状态下的活性污泥法处理系统,作为最优控制的研究对象。根据现代控制理论,在有出水水质和状态变量等约束条件下,建立能求出使目标函数为最小的最优控制和数学模型。最后,对这个数字模型,用计算机进行数值计算并绘图,求解出在几种不同的约束条件下,最优控制变量的变化规律。
The unsteady state activated sludge treatment system is studied as a research objective for optimal control in the paper. Based on the modern control theory,a mathematic model for optimal control is developed under the restrained conditions for effluent quality and the state variables, by means of which the minimum value of the objective function can be found out through solution. Finally, the numerical calculation and graph drawing of the mathematic model are carried out with a computer and CAD. As a result, the variable patterns on the variable of optimal control with time under several different restrained conditions are found out.
