摘要
利用温度传感器、变送器、PLC及其配套的A/D转换器件MAD02和上位计算机,以炉窑为被控对象,以炉窑出口气温为主被控参数,以炉膛内的气温为副被控参数,以加热炉电阻丝电压为控制参数,以PLC为控制器,设计了炉窑温度串级控制系统,运用PID算法进行了PLC程序设计,实现了炉窑气温的定值控制;经调试实验证明,综合误差仅为0.926℃,充分满足了本系统误差范围在2℃以内的控制要求。
Abstract; The use of temperature sensors, transmitters, PLC and its A/D conversion device MAD02 and the computer, with the furnace as the object to the furnace outlet temperature, main controlled parameter, in order to furnace temperature for secondary controlled parameters, with resistance wire of the heating furnace voltage as a control parameter, PLC controller, design of furnace temperature series level control system, using PID algorithm for the PLC program design, realization of the furnace temperature setpoint control. After the debugging experiment, comprehensive error of only 0. 926degrees C, fully meet the system error in the range of 2DEG C control requirements.
