Abstract

Aiming at the characteristics of non-linearity

pure lag and strong interference in the main steam pressure control of gas-fired power boilers

a first-order time-delay model of the main steam pressure sliding mode predictive optimization control strategy is proposed. The generalized predictive control is used to make real-time predictions of the gain and main steam pressure of the sliding mode controller. According to the prediction deviation of the main steam pressure

feedback correction and rolling optimization are exerted on the sliding mode gain to reduce the chattering of the sliding mode control system. By providing a nonlinear compensation to the flow characteristics of the gas control valve

the best control law in discrete form is obtained via optimizing the objective function. Compared with conventional PID control

sliding mode control and dynamic matrix control

the simulations show that the proposed control strategy during model adaptation reduces the adjustment time by up to 19.1 s and the overshoot by up to 16.4%; the sliding mode function chattering is small

and the system has good anti-interference

following and robust performances. The engineering application indicates that once adopting the proposed strategy

the system chattering is reduced by 60% compared with single sliding mode control

the main steam pressure control deviation is less than ±0.05 MPa

and the system stability and anti-interference ability are significantly improved.
