The design of gas boiler combustion system based on ADRC and μCOSII

As a heating equipment, gas boiler is widely used in daily production and life. Considering the security and stability of the control system of gas boiler, this article design a combustion controller based on ARM9. The μCOSII as a real-time operating system is transplanted into nuclear of MCU. For gas boiler is a non-linear, high inertia multivariate and multidisturbance etc, this paper adopts the active disturbance rejection control (ADRC) method. For μCOSII can divide the system into multiple tasks, it can improve security and stability of the system effectively. Besides, ADRC, as a advance control method, can improve the efficiency of system.
