电加热炉是典型工业过程控制对象,其温度控制具有升温单向性,大惯性,纯滞后,时变性等特点,很难用数学方法建立精确的模型和确定参数。而PID控制因其成熟,容易实现,并具有可消除稳态误差的优点,在大多数情况下可以满足系统性能要求,但其性能取决于参数的整定情况。且快速性和超调量之间存在矛盾,使其不一定满足快速升温、超调小的技术要求。模糊控制在快速性和保持较小的超调量方面有着自身的优势,但其理论并不完善,算法复杂,控制过程会存在稳态误差。 将模糊控制算法引入传统的加热炉控制系统构成智能模糊控制系统,利用模糊控制规则自适应在线修改PID参数,构成模糊自整定:PID控制系统,借此提高其控制效果。 基于PID控制算法,以ADuC845单片机为主体,构成一个能处理较复杂数据和控制功能的智能控制器,使其既可作为独立的单片机控制系统,又可与微机配合构成两级控制系统。该控制器控制精度高,具有较高的灵活性和可靠性。 2 温度控制系统硬件设计 该系统设计的硬件设计主要由单片机主控、前向通道、后向通道、人机接口和接口扩展等模块组成,如图l所示。由图1可见,以内含C52兼容单片机的ADuC845为控制核心.配有640 KB的非易失RAM数据存储器、外扩键盘输人、320x240点阵的图形液晶显示器进行汉字、图形、曲线和数据显示,超温报警装置等外围电路;预留微型打印机接口,可以现场打印输出结果;预留RS232接口,能和PC机联机,将现场检测的数据传输至PC机来进一步处理、显示、打印和存档。
