摘　　要：基于Rockwell PLC-5设计温度控制系统。为了便于实现比例-微分-积分控制器参数整定,对被控对象——电热箱进行实验建模;为了降低输入输出误差,对温度采集及变送环节进行实验建模;基于被建模型,采用改进欧拉法完成被控对象的数值仿真,提供数值仿真对象,可以方便进行控制参数整定,快速看到控制效果;采用模糊比例-微分-积分控制器,实现温度控制;基于Rsview完成人机交互界面和数据动态显示;完成了Rockwell PLC-5温度控制系统仿真平台和实际系统的开发,实现了温度控制系统演示实验和温度控制系统半开放实验设计,达到了预期的实验设计目标。The temperature control system is implemented based on Rockwell PLC-5.The heater case model is built by using experiment identification to easily find parameters of proportional-differential-integral controller.The sensor and transducer model is built by using experiment identification to decrease errors of input and output.Based on models built above,the numerical simulation is implemented by using improved Euler algorithm and the numerical plant is used as simulated plant to offer controlled results with different control parameters.The human-computer interaction and dynamic data display are implemented based on Rsview.The temperature control of simulation platform and actual heater case based on RockwellPLC-5 are implemented.Demonstrating simulation experiment and experiment with open controller are designed.Results show that experiments designed meet the design requirements.
