1. Brief Introduction

 

LU-926M memory type intelligent PID controller has various control methods and intelligent control adopts the combined control method of fuzzy theory and traditional PID,which enable the control process quick respond,small over modulation and high precision in stable state,especially has obvious effect on the large pure lag object which is difficult to be controlled by traditional PID.The control algorithm has auto-tuning function.

It has rich control mothods of set value,two setpoint registers,and can switch between external setpoint and event trigger setpoint.

Auxiliary 2nd sampling input can be as the external setpoint set values signal input and also can work with alarm source and transform source parameters setting to achieve differential algorithm alarm or differential algorithm transform. 

It is specially used in automatic control system of temperature, flow, pressure and level of light industry machines,ovens,test equipments,and heating/cooling equipment.,etc..
