Turbofan engines are known as the heart of aircraft. The turbofan’s health state determines aircraft’s operational status. Therefore, equipment monitoring and maintenance engine is an important part ensuring healthy stable operation aircraft, it vital to monitor remaining useful life (RUL) engine. monitored data turbofan have high dimensions a long time span, which cause difficulties in predicting This paper proposes residual prediction model based on Autoencoder Temporal Convolutional...
The role of control system for aero-engine is to provide sufficient thrust and maintain physical operational limits. Model reference adaptive (MRAC) technique has been paid more attention advantages in eliminating the effects uncertainties arising from nonlinearity or component degradation satisfying both safety performance requirements entire flight envelope. However, due accuracy models, implementation MRAC algorithm challenging. In this paper, an architecture based on equilibrium manifold...
Future gas turbine engine control systems will be based on a distributed architecture in which the sensors and actuators connected to controllers via communication network. The performance of (DEC) system is dependent network performance. network-induced time delay may degrade closed-loop even destabilize if are designed without considering effects delay. This paper introduces new method estimate maximum tolerance for analysis stability GE T700 turboshaft DEC system. sufficient conditions...
Modern aeroengine works under the harsh environment of higher temperature, pressure and speed, performance deteriorations its components is inevitable. In this article, an adaptive hybrid fault-tolerant control (AHFTC) system studied to deal with concurrent faults sensors actuators during deterioration engine health parameters by control. AHFTC system, proposed estimation method using thermodynamic nonlinear component-level (NCL) model merges process process, so that it can greatly improve...
Abstract The functional requirements of the control system in aero‐engine are increasing due to multiple objectives. typical is equipped with a multi‐loop and switches controllers achieve different performance requirements. However, fuel flow may be oscillated switch; this phenomenon can seriously damage aero‐engine, even its stability. Therefore, transient switching stability should concerned. This paper investigates bumpless compensator design problem for system. First, description bump...
Fuel control is usually required to work with the acceleration and deceleration schedules provide limit protection. However, protection will deteriorate controller performance. In this work, we investigate a model-based framework for gas turbine engine fuel system. First, performance degradation due actuator saturation in system described, thermodynamic component-level model small deviation linear are obtained from experimental data. Then, problem of antiwindup formed traditional static...
Due to the aero-engines in a high temperature, pressure, and spool speed environment, concurrent faults actuator/sensor combined with degradation of aero-engine could arise problem closed-loop instability during flight. For this purpose, an improved hybrid fault-tolerant control (FTC) technique has been studied paper deal simultaneous failure actuators sensors associated health parameters typical components’ aero-engines. The FTC structure nonlinear thermodynamic component-level (NCL)...
