Since the combustion system of coal-fired boiler in thermal power plant is characterized as
time varying, strongly coupled, and nonlinear, it is hard to achieve a satisfactory
performance by the conventional proportional integral derivative (PID) control scheme. For
the characteristics of the main steam pressure in coal-fired power plant boiler, the sliding
mode control system with Smith predictive structure is proposed to look for performance and
robustness improvement. First, internal model control (IMC) and Smith predictor (SP) is used …
