摘要
电阻炉中的恒温系统是非线性的,相当于一个时间常数很大的惯性环节,升降温缓慢,而且系统中没有专门的降温环节,针对被控对象存在的大惯性、纯滞后的特点,提出模糊控制与PID控制方式相结合的控制策略,设计了一种高精度温度控制算法.并以AT91M42800A单片机为核心,实现了该控制方案。
The character of APC system in resistance stove is nonlinear. According to the character of controlled body,great inertia and pure lag, the method, the conjoint between fuzzy and PID,is applied.The high precision method for temperature controlling is designed.The chip of AT91M42800A is key part;the project of controlling method is realized.
