The possibility of improving the automated control system of the steam generator in peak modes is being considered to improve the stability indicators, increase the speed and efficiency of heat and power systems. To implement the control, it is proposed to use nonlinear models of the control object and synthesize the control system by methods based on new conceptual foundations that allow taking into account the phenomena of interconnectedness and nonlinearity of processes in thermal power units. The method of analytical design of aggregated regulators (ADAR) was chosen as the synthesis method. In the course of computer simulation, it is demonstrated that the synthesized control laws ensure the asymptotic stability of a closed nonlinear system and the fulfillment of specified technological invariants. To demonstrate the effectiveness of the obtained synergetic laws of robust control, a comparison with traditional laws was performed. This comparison shows that with similar dynamic characteristics of transients, traditional laws do not provide the desired value and are operable in a smaller range of load speed changes.
