转窑温度控制系统转窑是一种工业生产过程的重要设备,许多工业原料的混和、烧结或干燥都是由这类设备进行的,窑内温度直接影响产品的质量。由于转窑的处理量是变化的,因此对象的特性亦跟随处理量变化。例如某转窑在额定工况下,加热燃烧的变化(带执行器的输入信号的变化)引起温度的变化(即温度变送器输出信号的变化),可用如下的传递函数来描述:
Rotary kiln temperature control system Rotary kiln is a kind of important equipment in industrial production process. The mixing, sintering or drying of many industrial raw materials are all carried out by such equipment. The temperature in kiln directly affects the quality of products. Since the throughput of a rotary kiln varies, the characteristics of the object also follow the throughput. For example, a kiln under rated conditions, the heating combustion changes (changes in the input signal with the actuator) caused by temperature changes (temperature transmitter output signal changes) can be used to describe the following transfer function:
