摘要
针对发酵过程中pH大滞后和时变性的特点,提出一种基于PLC的复合模糊控制算法,模糊控制器和PI调节器都通过PLC来实现,这样既保留了PLC控制系统控制灵活、可靠、抗干扰能力强等特点,又大大提高了控制系统的智能化程度。实践结果表明,该系统能有效抑制纯滞后的影响,而且鲁棒性强。
A compound fuzzy control algorithm based on PLC is presented to the large hysteretic and diverse characteristics of pH in the course of fermentation. The fuzzy controller and PI adjustor are realized by PLC. It not only holds the agile, reliable peculiarity and the ability of anti-jamming of PLC control system, but also improves consumedly the intelligentized level of control system. The practice resuits show that the system can effectively restrain the affect of pure hysteresis and has the strong adaptability.
