“…The architecture of the engine model Dynamic response of the engine is also considerably influenced by dynamics of the fuel pump with a non-linear element by-pass valve [2,9,21]. Transfer function of the valve can be expressed by the transfer function Fbypass (n), its operation being dependent on the engine's speed n. Fuel flow is partially transferred back into the engine up to a speed around 50 000 RPM.…”

Advanced control in the area of turbojet engines defines many different applied complex control strategies. Highly theoretical approaches and designs are often presented in this area. The article is aimed at practical aspects of adaptive controller design for a class of small turbojet engines in triple loop control architecture. The article presents a non-linear dynamic model of a small turbojet engine taking in account the environmental conditions, which it operates in. The designed triple loop control architecture shows increased precision of control keeping acceleration schedule of the simulated engine and is not susceptible to outer disturbances. The article shows pilot dynamic simulation tests, showing feasibility of the taken approach. It can also be used for other classes of turbojet engines as well other similar technical systems.

Abstract-In this paper, for the first time, a possible tackling of the problem of known time-delay by the use of a Fixed Point Transformation-based adaptive controller is investigated. This approach at first transform the control task into a fixed point problem then solves it via iteration. The preliminary results that were obtained by numerical simulations for a strongly nonlinear controlled system, a van der Pol oscillator, are promising. It is expedient to make further, systematic investigations.
