This paper presents an active disturbance rejection control method for stochastic disturbance suppression in the heating furnace based on the reset state observer, aimsing to solve the problem that serious disturbance exists in the temperature control of heating furnace. The main idea of this method is that the influence of stochastic disturbance on the states is reduced to that on the output and is compensated actively. Firstly, an active reset state observer is designed to track the states of plant quickly. Then, a stochastic disturbance estimator is designed to estimate the value of these disturbance which is put to the input channel. Finally, the active disturbance rejection control system for stochastic disturbance suppression in the heating furnace based on reset state observer is designed. Simulation result shows the effectiveness and superiority of the proposed approach.
