The paper describes the establishment of a boiler control implemented on laws of fundamental physical system, effects of modelling of boiler, data of plant, constant of known physical, and adjustment of heuristic. The objective of this work it to find the modelling of the steam generator and steady the properties of the outputs to find the suitable controller. The model involves the nonlinearity mathematical model, noise of measurement, and time delays. The model represents by state space equations for each variable to describe the whole model system. The model acquired can be utilized for the algorithm for modelled-based control as a simulator of real- time for controlling and operating system. The suggested control for this system will be state feedback control to decrease the peak overshoot for each response of outputs have been seen to maintain the stability and performance.
