(五)在过程控制中,往往要求系统按照环境的情况或变化自行调整系统参数,以使表征控制系统优劣指标的目标函数到达极值,这就是自寻最优控制,而利用计算机实现控制系统的自寻最优是较容易的。自寻最优的方法有很多,诸如依次搜索法、盲目搜索法以及梯度法等等。梯度法是多变量极值系统中最常用的一种方法。本篇以两个例子说明自寻最优程序设计方法。例子中采用的都是梯度法。
(E) In process control, often require the system to adjust the system parameters in accordance with the circumstances or changes in the environment, so that the objective function that characterizes the advantages and disadvantages of the control system reaches the extreme value, which is to find the optimal control, and the use of computer control The best of the system is easier to find. There are many ways to find the best, such as sequential search method, blind search method and gradient method. Gradient method is the most commonly used method in multivariate extreme value system. This article uses two examples to illustrate how to find the optimal program. Examples are used gradient method.
