摘要
在现实生产中,为了更好地对设备进行控制,实现其稳定、快速,保证其准确性,就必须对设备进行建模。对被控对象特性的深入了解是控制的核心部分,也是是控制系统设计方案的主要依据。研究系统建模实现方法,应用电子器件构建模拟电路,在电路输入端加阶跃信号,应用示波器采集输入输出数据,应用两点法、辨识工具和最小二乘法、神经网络法分别进行系统建模。
In actual production,in order to better control equipment and realize its stability,fast speed and accuracy,it is necessary to conduct equipment modeling.Therefore,an in-depth understanding of the characteristics of the controlled object is the core part of control,and also the main basis of the control system design plan.In this paper,the system modeling realization method was studied,electronic devices used to construct analog circuits,step signals added at the input of the circuit,an oscilloscope used to collect input and output data,and a two-point method,identification tools and least square method and neural network method were used respectively for system modeling.
