介绍在以 PC 机作为下位机操作站时, 利用ActiveX 技术创建完成模糊自调整 PID 算法的Activ eX 控件,并内嵌在组态环境中, 实现对现场的监控和实时控制。实践表明该控件对不确定性和时变性的对象具有一定的适应性。-Introduction to PC as lower operating stations, the use of ActiveX technology to create a complete fuzzy self-tuning PID algorithm Activ eX control, and embedded in the configuration environment, on-site monitoring and real-time control. The practice shows that a certain degree of adaptability of the control of uncertainty and time-varying object.
