摘要
针对电阻炉温度系统具有非线性、大惯性、大滞后等特点,结合常规PID控制器和模糊控制器各自的长处,以MATLAB为计算平台,通过OPC技术实现MATLAB和ECS-700之间的数据交换。提出了基于OPC技术的自适应模糊PID控制方案。自适应模糊PID控制器由MATLAB中的模糊工具箱设计,ECS-700主要负责数据采集和设备驱动。实验结果表明,电阻炉温度控制系统的性能令人满意,该方法调节时间短、超调量小、波动小,OPC通信的性能非常有效可靠,可以有效应用于电阻炉温度控制系统中。
For resistance furnace temperature system has the characteristics of nonlinear, big inertia, great lag, combined with respective strengths of the conventional PID controller and fuzzy controller, and taking MATLAB as computing plat- form, the data exchange between MATLAB and ECS - 700 is realized by OPC technology. The paper puts forward the adap- tive fuzzy PID control scheme based on OPC technology. The adaptive PID controller is developed by the fuzzy toolbox in MATLAB. The data acquisition and devices driving are also realized by ECS - 700. The experimental results show that the performance of resistance furnace temperature control system is satisfactory and the method has short setting time, small o- vershoot and fluctuation, simultaneously the performance of OPC communication is very efficient and reliable ,which deter- mines the system can be effectively applied in a resistance furnace temperature system.
