摘　　要：基于虚拟仪器编程软件LabVIEW并结合使用数学软件MATLAB,开发了一套基于LabVIEW编译环境的多步滞后自校正控制系统。利用LabVIEW与MATLAB混合编程,采用最小二乘法进行参数辨识和最小方差模型预报,实现系统的自校正控制。We combine LabVIEW, a virtual instrument programming software, with MATLAB, a powerful mathematics software, in order to develop a set of excessive step-lagging self-tuning control system based on LabVIEW editing environment. Mixing LabVIEW programming with MATLAB and using the least square method to carry on the parameter identification and forecast the smallest variance model, a self-tuning control system is realized. It can be seen that the design capability of developing virtual instruments is improved with the combination of LabVIEW and MATLAB.
