基于VB与MATLAB接口的纯滞后系统仿真界面

Realization of pure delay system simulation interface based on VB and MATLAB interfacing

应用VB与MATLAB的接口编程,实现脱离MATLAB环境的人机界面功能。针对纯滞后一阶和二阶系统的大林算法和SMITH预估控制算法的MATLAB仿真过程,介绍了通过选择6种不同输入信号可以方便地得到相应系统的PID算法、大林算法及SMITH算法的仿真结果。该人机界面可以灵活调整参数,以便得到不同的仿真效果。同时界面具有能够直接输入MATLAB一切命令的区域,便于课堂教学演示。

Interfacing programmed of VB and MATLAB was applied to realize man-machine interface function disengaged MATLAB environment. The MATLAB emulation course of dahlin algorithm and SMITH prediction control algorithm of first order and second order system of pure delay were contraposed. The emulation results of PID algorithm, dahlin algorithm and SMITH algorithmic by selection of six-imported signal were obtained. The man-machine interface can agility adjust parameters to get different emulation effect. At the same time, interface has the region of directing input of wholeness MATLAB commands. It convenients for classroom instruction demonstration.
