Abstract

This paper presents a multi-mode control scheme for the temperature regulation of radioactive waste incineration equipment, integrating modern and fuzzy control theories. Separate controllers were designed for the preheating and operating stages. In preheating phase, a mathematical model was developed using mechanism modeling, enabling automatic control through sequential and proportional-integral-derivative control. For operation phase, a composite control approach combining fuzzy control and special variable ratio control was proposed. The fuzzy controller used temperature difference, changing rate and acceleration as inputs, adjusting oxygen concentration to regulate combustion temperature. Experimental results demonstrated 27 h of stable automatic control with a maximum temperature deviation of 9.1 °C and an error rate of 1.65 %. The proposed scheme provides specific control strategies with quantifiable performance indicators, proving its effectiveness in maintaining temperature stability in radioactive waste incineration.

放射性废物焚烧设备温度复合控制系统的研究

结合现代控制理论和模糊控制理论，提出了一种放射性废物焚烧设备温度调节的多模式控制方案。对预热段和运行段分别设计了控制器。在预热阶段，利用机理建模建立数学模型，通过顺序控制和比例-积分-导数控制实现自动控制。在运行阶段，提出了模糊控制与特殊变比控制相结合的复合控制方法。模糊控制器以温差、变化率和加速度作为输入，通过调节氧气浓度来调节燃烧温度。实验结果表明，自动控制稳定27 h，最大温度偏差为9.1℃，错误率为1.65%。该方案提供了具体的控制策略和可量化的性能指标，证明了其在保持放射性废物焚烧温度稳定性方面的有效性。
