摘要 介绍近年来新发展的随机分布控制的基本思想、建模、控制和应用。讨论了线性、平方根和有理3种B样条模型表示形式,将概率密度函数模型转化为权向量模型。以线性B样条模型为例介绍了控制器设计的一般原理。对离散线性动态系统,输出概率密度函数和输入之间存在一个简单的回归模型,采用二次型瞬间性能指标,可以得到控制量的最优闭环结构。结合造纸、化工、粮食加工和燃烧过程,讨论了方法的应用前景及如何获取概率密度函数这一关键问题。 Main ideas and recent development of the probability density function (PDF) cont rol are reviewed.Three B-spline models are used to model the output P DF and therefore transform the PDF model into the weights model.A general contr oller design principle is given based on the linear B-spline model.The output PDF is related to the input by a simple ARMA model for the linear,discrete-time dynamic system,from which an optimal closed-loop solution is obtained analytic ally using an instant quadratic performance.Several industrial applications are discussed and solutions to the bottle-neck problem of how to obtain the output PDF is suggested.
