非线性PID控制在液位控制系统中的应用

Application of Non-linear PID Control in Fluid Position Control System

针对液位控制系统的大时滞、不稳定性,常规PID控制很难满足要求,提出带有死区的非线性PID控制,实际运行验证了该方法的有效性。

The fluid position control system has big time lag and instability,the conventional PID control is very difficult to satisfy the request,this article proposed one non-linear PID control which has the dead area,the actual movement has confirmed the validity of this method.
