摘　　要：采用衰减曲线法对被控对象进行PID参数整定,以达到最佳的控制状态。进行增量式PID控制算法的设计,并由MATLAB语言编程实现。采用VB进行人机界面的设计,以实现与MATLAB的接口编程,该人机界面可以灵活调整参数。采用COM(component objectmodel)技术来实现VB与MATLAB之间的数据交换,将PID整定参数及被控对象参数通过COM接口传递到MATLAB,由MATLAB完成控制算法的计算,并将计算结果返回至VB,由VB完成曲线的显示。PID parameter tuning is performed based on attenuation curve to achieve the best control state.The increasing PID controlling algorithm is designed and implemented by MATLAB programming.The man-machine interface is designed by VB,which can adjust parameters flexibly.Data exchanging between VB and MATLAB is implemented by COM.The PID tuning parameters and process object parameters are delivered to MATLAB through COM interface,and then control algorithm is completed by MATLAB,and the result is returned to VB.
