摘要
Abstract
The boiler steam pressure is a important parameter reflecting the state of boiler operation. According to the delayed measurement of the boiler steam pressure, a delayed output observer was designed for fuel-steam pressure system. In the delayed output observer, only the boiler steam pressure was needed, then the observed value of the boiler steam pressure, the first derivative and the second derivative value of the boiler steam pressure were obtained. The convergence of the observer was proved. Sliding mode controller was designed by using the observed value which can improve the system robustness, and the result show that the closed system stability can be guarantee from Lyapunov stability analysis. Only the boiler steam pressure signal was used in the observer and the controller, which indicates that the proposed method has important significance in engineering. Simulation results are presented to validate the good tracking performance of the control system.关键词
