Abstract

Non-normal residuals in rule-based wastewater controllers undermine reliability and hinder statistical monitoring. This study resolves the issue by fusing a zero-order Sugeno fuzzy-inference system with a real-coded genetic algorithm that jointly tunes rule weights and membership functions while steering errors toward Gaussian form. Fuzzy-cognitive mapping reduces the candidate rule set to five dominant rules, which are then optimized on a training–testing split from a full-scale plant. The resulting controller lifts the treated-water-quality index from 51.08 to 69.28, lowers mean-squared error and attains a test RMSE of 0.03; the residual standard deviation is virtually identical, confirming a near-normal error distribution.

从混沌误差到自然曲线:污水处理系统的实编码遗传校准
基于规则的废水控制器中的非正态残差破坏了可靠性并阻碍了统计监测。本研究通过将零阶Sugeno模糊推理系统与实数编码遗传算法融合来解决这个问题,该算法联合调整规则权重和隶属函数,同时将误差转向高斯形式。模糊认知映射将候选规则集减少到五个主要规则,然后在全尺寸工厂的训练-测试分裂上进行优化。该控制器将处理后水质指标从51.08提高到69.28,均方误差降低,检验均方根误差(RMSE)为0.03;残差标准差几乎相同,证实误差分布接近正态分布。

期刊介绍: International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management. A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made. The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
