An aero-engine U-control method based on LPV model
Chen, Jiajie; Wang, Jiqiang; Hu, Zhongzhi; Dimirovski, Georgi Marko (Elsevier, 2020)Due to the harsh working environment and various constraints, the engine control unit (ECU) has very limited computational ability and few control methods can be applied to the real-word ECU maturely. Developing advanced ... -
Aircraft turbine engine control systems development: Historical perspective
Lutambo, Jackson; Wang, Jiqiang; Yue, Hong; Dimirovski, Georgi M. (IEEE, 2015-07)This paper describes the development of aircraft turbine engine control systems from the historical point of view to the present. With the increasing emphasis on aircraft safety, enhanced performance, and affordability, ... -
A comparative study on optimal transient control of aircraft engines
Gao, Yang; Wang, Jiqiang; Wu, Xin; Ye, Zhifeng; Hu, Zhongzhi; Dimirovski, Georgi M. (Springer, 2016)Sequential quadratic programming has been widely used in the optimization of transient control of aircraft engine. On the other hand, the study of nonlinear optimization theory and method has been made great advance in ... -
Complexity of constrained switching for switched nonlinear systems with average dwell time: Novel charecterization
Dimirovski, Georgi M.; Wang, Jiqiang; Yue, Hong (IEEE, 2016-10)In so far developed theory of switched systems is largely based on assuming certain small but finite time interval termed average dwell time, which represents a constraint even when extremely small. Thus currently most of ... -
Disturbance attenuation in linear systems revisited
Wang, Jiqiang; Yue, Hong; Dimirovski, Georgi M. (Springer, 2017-08)A variety of methods have been proposed for attenuating or rejecting disturbances in linear systems. Most of the approaches, however, are targeting the performance either near resonance or across the whole frequency range. ... -
Fast response control of turbofan engines using a finite time approach
Wang, Jiqiang; Dimirovski, Georgi M.; Yue, Hong (IEEE, 2014-07)Increasing requirements from flight control demand fast regulation of engine control systems. This has motivated research on advanced control of turbofan engines. One of the attempts is to employ nonlinear design techniques ... -
Finite-time regulation of two-spool turbofan engines with one shaft speed control
Wang, Jiqiang; Dimirovski, Georgi M.; Yue, Hong (The American Society of Mechanical Engineers, 2016-08)Nonlinear control of aircraft engines has attracted much attention in consideration of the inherent nonlinearity of the engine dynamics. Most of the nonlinear design techniques, however, require the information from the ... -
Model-based acceleration control of turbofan engines with a hammerstein-wiener representation
Wang, Jiqiang; Ye, Zhifeng; Hu, Zhongzhi Z.; Wu, Xin; Dimirovski, Georgi M.; Yue, Hong (De Gruyter, 2017-05)Acceleration control of turbofan engines is conventionally designed through either schedule-based or acceleration-based approach. With the widespread acceptance of model-based design in aviation industry, it becomes necessary ... -
Performance cycle analysis on turbo fan engine PW4000
Benawra, Shray; Wang, Jiqiang; Yue, Hong; Dimirovski, Georgi M. (IEEE, 2015-07)This paper describes an effort to investigate and better define the capabilities of a modern mathematical solver in predicting the in on-design performance of a turbo fan engine PW4000. The results will validate the use ... -
WAN networked control systems implemented by computer control: Sampled-data synthesis
Dimirovski, Georgi M.; Liu, Yunlong; Wang, Jiqiang (IEEE, 2017)A novel discrete-time synthesis for WAN-based computer control of networked control systems with a class of nonlinear plants is developed. Such a networked control systems are assumed to comprise an affine nonlinear plant ...
