一类以非线性方式使用微分信息的PID调节器及其应用

A PID Controller with a Nonlinear Differentiator and Its Applications

本文讨论了一种能提供相位超前但不放大高频噪声的非线性微分器,用它构成非线性PID调节器并用于热工对象的控制,取得了优于线性PID的效果。

This paper describes a kind of nonlinear differentiator which provides phase lead without amplifying the high frequency noise. The differentiator is incorporated in a controller to form a nonlinear PID controller which can control a thermodynamic process with an effectiveness surpassing that of a linear PID controller
