LU-906K Easy-to-Use Intelligent PID Controller
Controller for temperature control, flow measurement and control, pressure regulation and level control.
I. Overview
The LU-906K "foolproof" smart PID controller is a new generation of easy-to-use smart controller developed on the basis of the LU-906M smart program controller, with its control algorithm and auto-tuning function optimized and some functions simplified. It inherits the advantages of fuzzy PID and artificial intelligence control—fast response, small overshoot, and high steady-state accuracy—and eliminates the need for manual PID parameter setting: with a simple key press, the instrument automatically completes PID parameter setup, delivering a truly foolproof function.
The LU-906K "foolproof" smart PID controller uses an advanced ATMEL single-chip microcomputer as the host, reducing peripheral components and improving reliability. It integrates multiple input types, output modes, and control modes in one unit. By combining fuzzy theory with conventional PID control, it achieves fast response, small overshoot, and high steady-state accuracy, and shows a clear control effect especially on objects with large pure lag that are difficult to control with conventional PID.
The hardware adopts a WATCHDOG circuit, and the software adopts redundancy, trap, and other noise-immunity techniques. The instrument offers very high reliability and can operate in harsh environments. The dual 4-digit LED display can show the measured value and setpoint or the measured value and output value simultaneously. It provides bumpless manual/automatic switching, auto-tuning, and a soft-start function on power-up.
The LU-906K "foolproof" smart PID controller is widely used in automatic control systems for temperature, flow, pressure, and level in chemical, ceramic, light industry, metallurgy, petrochemical, heat treatment, and other industries.
