摘要:

基于Matlab仿真的传统PID实验系统,不仅缺少实际控制对象,且存在一定的抽象性。为了完善该系统,设计实现了一种基于工业模型的新型PID实验系统。该系统在原有仿真实验的基础上,增加了工业电机控制模型,并以LPC2114为核心处理器,L298N为电机驱动的直流电机控制系统,通过Matlab编程进行PID实时控制。实验证明,该系统不仅保留了Matlab仿真实验的准确性,更能体现出PID参数变化对系统的影响,展现了PID的工业控制效果,提高PID实验系统的直观性。

Abstract:

Traditional PID experimental systems based on Matlab simulation are not only short of actual control objection but also abstract.This paper designs and implements a new PID experimental system based on the industrial model.The industrial motor control model is added to the original simulation with LPC2114 as the core processor and L298N for the DC motor control system of motor driven.PID real-time control is performed by Matlab programming.The experiment proves that the system reflects the influence of PID parameter changes on the system and the effect of PID industrial control while retaining the accuracy of the Matlab simulation experiment,and improves the visibility of PID experimental system.
