Abstract

Abstract: Based on the linear simplification of the ADRC controller, this study presents a method of tuning the relevant parameters in accordance with the request of the close-loop system’s response and applies the method in the drum-level cascade three-impulse control. The Matlab simulation results show that this linear ADRC(LADRC) requires less tuning parameters, and is simple to operate. It can meet the requirements of the steady-state response of the system, and has good robust for all kinds of interferences which makes it to stand out from the traditional ones. Therefore, the LADRC is an ideal choice for a large number of thermal-controlled objects with uncertain model in practice, and is good for promotion and application.

Key words: boiler, linear ADRC, drum water-level, cascade three-element control
