Abstract: In this article the simultaneous solution of identification task and linear adaptive controller synthesis (with the state or output feedback) is offered for the following cases:
– synthesis on the sensibility criterion is realized by the way of selected sensibility measure minimization with respect to object parameters;
– mathematical model and rearrangement algorithm of the parameters controller is defined on the adaptive synthesis.
By the way desensitization to object parameters variation is realize by insertion the quadratic sensibility members to the subintegral expression of loss functional.
Computing procedure of an uncertain object control system synthesis is considered.
The effectiveness of received investigation results is given a demonstration of adaptive control system of gas-turbine system of power station. The algorithm of control signals generation is realized with using Assembler in MPLAB environment for microcontroller PIC16F877. Modeling results of gas-turbine control system of power station on the basis of adaptive control with reference model is offered and investigated in this article.

Keywords: uncertain object, adaptive control with reference model, gas turbine (power) plant.
