如何应用Ziegler_Nichols(Z-N)法整定PID调节器的参数
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 ...
5. 针对超调和振荡的情况适当增加微分项。 以上5个步骤可能是大家在调节PID控制器时的普遍步骤,但是在寻找合时的I和D参数时,并非易事。如果能够根据经典的Ziegler-Nichols(ZN法)公式来初步确定I和D元件的参数,会对我们的调试起到很大帮助。 John Ziegler和Nathaniel Nichols发明了著名的回路整定技术使得PID算法在所...

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）...
