本文从电阻炉温控系统PID调节器的角度,分析关于大惯性、非线性、纯滞后环节中的数学模型,并按比例、积分、微分线性的组合构成数字化PID调节器,通过调试得到其结论,找到因果关系及改进办法,在其领域内用理论来指导今后的实际应用。
This paper analyzes the mathematical model of high inertia, non-linearity and pure hysteresis from the point of view of the PID regulator of resistance furnace temperature control system. Based on the combination of proportional, integral and differential linearity, a digital PID regulator is constructed, and its conclusion is obtained through debugging , To find the cause and effect and ways to improve, in its field with theory to guide the future practical application.
