Application of generalised predictive control to a boiler-turbine unit for electricity generation

Linear control of a boiler–turbine unit: Analysis and design

“…The control of boiler-turbine units has been widely studied in the literature using various control techniques, e.g., robust control [2][3][4]; nonlinear control [5]; predictive control [6][7][8][9][10]; and intelligent control [11][12][13][14][15]. While these methods are effective, the following problems make the advanced control methods listed above to be seldom applied in practice:…”

Multivariable PI control for a boiler plant benchmark using the Virtual Reference Feedback Tuning

“…The literature on boilers and boiler control is extensive. In rather recent papers, pole placement control was applied to a six order boiler model in Anakwa and Swamy (1988) while General Predictive Control (GPC) was applied in Hogg and El-Rabaie (1991) in a coal fire boiler, in Rossiter et al (1991) for a boiler in a power station and in Xu et al (2005) in a cascade control topology for drum level control with identified CARIMA models. In Dimeo and Lee (1995), genetic algorithms are used to tune a PI controllers with extra proportional gains for decoupling for a boiler-turbine plant.…”

Long range predictive PID control for nonlinear boiler-turbine dynamics

“…Thus, as operating conditions change the system performance will not be optimal [4]. Engineers usually take power plants as a time-variant system and try to compensate the variations of the model parameters by robust techniques [5] and self-tuning techniques [6].…”
