摘 要

随着科学技术的不断进步,温度控制系统中常用的是控制参数,而利用MATLAB控制这些参数已成为当今主流。在PID控制器的设计中,随着计算机技术的飞速发展,参数整定是最重要的,PID的设置大多是基于一些先进的软件。MATLAB仿真软件广泛应用于本设计中的继电反馈法、在线综合法和系统辨识法来研究PID控制器的设计方法,并使PID控制器的温度控制系统,并在MATLAB中使用虚拟示波器,在系统完善之前,观察阶跃信号的输出波形,得到干扰信号响应曲线的抗干扰性,经过对比得出了,在有了干扰信号时,该系统可以很好地控制系统的干扰信号,将干扰信号引入系统中是十分必要和可行的。

ABSTRACT

With the continuous progress of science and technology, control parameter is commonly used in the temperature control system. And using the MATLAB to control those parameters has become the mainstream. In the design of PID controller, with the rapid development of computer technology parameter tuning is the most important thing. The PID Settings are mostly based on some advanced software. MATLAB simulation software is widely applied to the relay feedback method, Online variety legal and system identification in this design to study the design method of PID controller. And using the PID controller's temperature to control system, use a virtual oscilloscope in MATLAB. Before the system is perfected, observing the output waveform of the step signal and obtaining the interference of the signal response curve. By contrast, when there is an interference signal, the system can control the system's interference signal very well. It is necessary and feasible to introduce interference signals into the system.
