Virtual Design of Advanced Control Algorithms for Small Turbojet Engines

Abstract

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.

A Simple Soft Computing Structure for Modeling and Control

“…Another practical example is modeling turbojet engines. Observation of the real physical state of the system needs sophisticated indirect experiments as measuring the near magnetic field [17], application of thermal imaging-based diagnostics [18] while for control purposes much simpler models can be applied in "situational control" (e.g., [19][20][21]).…”
