摘要
目前工业生产过程中广泛采用工控组态软件实现实时监控。在工控组态软件环境中对不同组态的控制算法的性能进行仿真与优化在工程实际中具有实际意义。采用Matlab结合力控自动化组态软件,通过Excel的DDE数据传送方式,进行传动系统试验台系统特性的在线模型辨识,用遗传算法对PID参数优化分析等半实物仿真技术。以力控组态软件为例给出了仿真系统的结构组成,数据及参数相互传递的仿真和应用于传动系统试验台的PID优化控制的实例。
The industrial configuration software is popular in real time supervising of the process product.The simulation and optimization of dif- ferent control arithmetic is of fundamental importance for economic reasons.A hardware in loop simulation(HILS)approach which uses dynamic data exchange(DDE)between configuration software and Matlab through Excel is intredaced.The proposed technology aims at realizing online identification via PC-based hardware,and carrying on PID parameters optimization of vehicle transmission system using genetic algorithm provid- ed by Matlab.The structure of simulation system is designed,which adopt DDE to exchange data and parameters.Test bench example shows that the approach can improve the performance of vehicle transmission system under PID control.
