摘要
针对工业电阻炉温度控制的非线性、大惯性和大滞后等问题,设计一种基于PID分段式温度控制系统。在分析传统PID控制技术的基础上,对其进行改进,为验证温控系统控制性能,对电阻炉进行基本PID和位置式PID分段控制实验。结果表明:与常规PID控制相比,PID位置式控制算法能实现多通道和分段式温度控制,具有超调小、精度高和稳定性好等优点。
In view of nolinear, strong inertia and heavy delay questions of industry fuzzy temperature control system, a step-shaped temperature control system based on PID was designed. Based on analysis of conventional PID control technology, we make the improvement to it and carry on basic PID and the step-shaped position type PID control experiments with the fuzzy to confirm the systems control performance. The result indicated that compares with the conventional PID control, the control algorithm of position PID can realize the multichannel and the step-shaped temperature control, has the little over modulation, the high precision and good stability and so on merits.
