在自动控制系统中,PID(比例-积分-微分)控制器被广泛用于调节各种工业过程。为了使 PID 控制器达到最佳的控制效果,需要对其参数进行调节。Ziegler-Nichols 闭环法是一种经典的 PID 参数整定方法,它通过实验性的方法帮助工程师快速找到合理的 PID 参数。本文将详细介绍 Ziegler-Nichols 闭环法的原理、步骤和应用。 1 ...
Ziegler-Nichols 闭环法的步骤 2.1 建立闭环系统 首先,将 PID 控制器接入到需要控制的系统中,形成一个闭环控制系统。这意味着传感器、控制器和执行器之间形成了一个反馈回路。 2.2 关闭积分和微分作用 在开始整定之前,将 PID 控制器的积分(Ki)和微分(Kd)作用关闭,只保留比例作用(Kp)。这可以通过将 Ki 和 Kd ...
本文将介绍Ziegler-Nichols整定PID的方法,它最初是在1940年代由两位泰勒仪器公司的工程师提出,这个方法也因此以二人的名字命名。这种方法的基本思路是将积分和微分增益设置为0,然后比例增益从零开始逐渐增加,直到达到极限增益Ku,并获得此时的振荡周期Tu。然而传统的方式需要你借助仿真工具多次尝试,且测得的振荡周期Tu也...

1. Ziegler-Nichols方法是PID控制器参数整定的常用技术之一,它通过观察系统的响应来确定比例系数(Kp)和震荡周期(T)。2. 首先,系统被设置为等幅震荡,这意味着系统输出会在一个稳定的振幅附近上下波动。这个状态是系统在临界稳定条件下的表现。3. 在系统达到等幅震荡状态时,记录下比例系数(Kp)...
