Abstract

The approach to synthesis and development of multidimensional fuzzy interval-logic regulators in the created visual programming environment that generates the program code of regulators for Simatic S7-300 and S7-400 controllers is considered. Multidimensional interval-logic regulators use the mathematical apparatus of fuzzy regulators with mixed (trapezoidal and rectangular) membership function µ equal to one. The proposed modification of regulators is the author’s development and is intended for use in control systems with a sufficiently large volume of product rules describing the logic of a complex technological object without an adequate mathematical model. The software of the visual development environment takes into account the requirements of the current editions of IEC 61131-3 and 61131-7 standards. The basic variant of the block diagram of a multidimensional interval-logic regulator is presented. Schemes for the interpretation of continuous physical quantities by an equivalent set of terms are given. The proportional deintervalization algorithm is formulated. It is shown that the synthesis and programming of this modification of fuzzy regulators consists in determining the vectors of terms of input and output continuous variables, as well as the mutual relations between them, compiling a system of production rules and selecting the appropriate algorithm of deintervalization. The approach to the development of multidimensional interval-logic regulators by means of special software tools (editors and applications) included in the visual development environment is described. The proposed approach provides a clear and quick creation of controller functional blocks for Simatic S7-300 and S7-400 programmable logic controllers. At the same time, it is possible to analyze and simulate the work of the system of production rules and regulators as a whole, which reduces the time of development and debugging of control systems based on them.
多维模糊区间逻辑调节器的可视化编程环境
考虑了在生成Simatic S7-300和S7-400控制器稳压器程序代码的可视化编程环境中合成和开发多维模糊区间逻辑稳压器的方法。多维区间逻辑调节器使用模糊调节器的数学装置,其混合(梯形和矩形)隶属函数μ等于1。拟议的调节器修改是作者的发展,旨在用于具有足够大容量的产品规则的控制系统,这些规则描述了没有适当数学模型的复杂技术对象的逻辑。可视化开发环境的软件考虑了当前版本的IEC 61131-3和61131-7标准的要求。给出了多维区间逻辑调节器框图的基本变体。给出了用一组等价项解释连续物理量的格式。提出了比例反间隔算法。结果表明,这种模糊调节器修正的综合与规划包括确定输入输出连续变量项的向量及其相互关系,编制生成规则系统,选择合适的去区间化算法。描述了通过可视化开发环境中包含的特殊软件工具(编辑器和应用程序)开发多维间隔逻辑调节器的方法。所提出的方法为Simatic S7-300和S7-400可编程逻辑控制器提供了清晰快速的控制器功能块创建。同时,可以对整个生产规则和调节器系统的工作进行分析和模拟,从而减少了基于它们的控制系统的开发和调试时间。
