摘要

在人造板甲醛释放量快速检测装置中,温度控制过程具有非线性、时滞性、时变性等特点,难以建立精确的数学模型。为此开发了模糊PID温度控制系统,在线自动调整PID控制参数,适应被控过程参数的变化。应用结果表明,与常规PID控制算法相比,该算法的系统稳定性、响应速度、超调量和稳态精度等均有明显改进,控制效果良好。

Abstract

In chambers for accelerated testing formaldehyde emissions from wood-based panels, temperature was indirectly regulated by water circulation.Due to non-linearity,time delay and time variation of the temperature control,it was hard to build a precise mathematical model for the process.A fuzzy adaptive Proportion-Integration-Differentiation（PID）controller was designed and developed,which could automatically adjust the PID parameters and to adapt changing arguments in the controlled process.Compared with conventional PID control algorithms,the control effect of a fuzzy-PID algorithm could greatly improve system stability,responding speed,overshoot and steady state accuracy.
