| 摘 要： | 在Wincc中开发的趋势图具有直观性和易操作性的基础上，采用SIMATIC和Wincc软件通信的方法，使用S7 300PLC软件自带的FB41功能块和通过编程设计的FB100功能块对整个闭环控制系统进行模拟。在Wincc中开发出用于PID参数整定的趋势图画面，调节趋势图中IO域的参数，根据生成的跟随信号的波形对PID控制器的参数进行整定。通过对闭环控制系统的仿真实验，得到了在方波给定信号输入下准确稳定的跟随信号，其中比例系数为2.00，积分时间和微分时间分别为10 000 ms和2 000 ms。

| Abstract: | The trend of development in the Wincc figure on the basis of intuitive and easy operability, adopt the method of SIMATIC Wincc software and communication, S7 300 PLC software used to own FB41 function block and through the programming design of FB100 function block used for simulating the whole closed-loop control system.Developed in the Wincc trend chart picture for PID parameters setting, adjust the parameters of trend diagram IO domain, according to the following signal waveform generated for setting the parameters of the PID controller.Through the simulation experiments of closed-loop control system, get under the square wave signal input given accurate stability following the signal, the proportion coefficient is 2.00, integral and differential time 10 000 ms and 2 000 ms respectively. |
