Currently, multi-mode control is widely used in the management of complex controlled objects. The actual solution of this article is the replacement of the dynamic situation analyzer by the state controller by the example of controlling the air jet engine. The state of the air jet engine is characterized by the following variables: the rotary frequency of the free turbine (fan or low-pressure compressor), the rotary frequency of the high-pressure compressor, the pressure and combustion temperature of the gas in the combustion chamber, etc., which are projections of the state vector, where the operating point in the current time moves on the static characteristic. All variables depend on the fuel consumption, its quality and synchronously change at the current time. Currently, all listed parameters of the air jet engine are regulated separately, which is a disadvantage. It is proposed to replace the linear regulators of the above parameters with a single state regulator that controls the dispenser of an air jet engine. The task of the fuzzy adaptive controller state is to change the fuel consumption of the dispenser in order to control the parameters for implementing the various operating modes of the air jet engine using neural-fuzzy technology. The developed model of the state controller meets the requirements of the real-time system, and reduces the hardware costs for building the control system by eliminating the selector.
Keywords: air-jet engine, sensors, dispenser, adaptive fuzzy state controller, selector
