Application of Unconstrained Controllers for a Linearized Benchmark Boiler

Boilers are still used in power plants and other industries for various purposes. Controlling and monitoring of crtical parameters of a boiler are very important. The safety of the process is monitored by proper control strategy. Control of a drum boiler primarily involves pressure inside the boiler, level of drum water and flow of steam outlet at required levels. Interactions among the variables are the issues of a controller. In this paper, model predictive controller (MPC) and linear quadratic regulatory (LQR) controller are applied to a linearized benchmark boiler. Comparison between Dynamic Matrix Controller (DMC) and Linear Quadratic Regulatory Controller are studied and results are presented.
