LPV Controller Design for Diesel Engine SCR Aftertreatment Systems based on Quasi-LPV Models
2021 American Control Conference (ACC), 2021This letter presents linear parameter-varying (LPV) controller design for the urea-based selective catalytic reduction (SCR) system in diesel engines to reduce nitrogen oxides (NOX) and ammonia (NH3) emissions. Although such LPV SCR controller design has been previously developed, this letter extends it in various ways. The extension includes the usage

Output-feedback stabilization of singular LPV systems subject to inexact scheduling parameters
Automatica, 2019This paper is concerned with the output-feedback stabilization problem for a class of singular linear parameter-varying (LPV) systems. The objective is to design a dynamic output-feedback controller such that the resulting closed-loop system is robustly ...

Engine EGR Valve Modeling and Switched LPV Control Considering Nonlinear Dry Friction
IEEE/ASME transactions on mechatronics, 2020Exhaust gas recirculation valves used in internal combustion engines are highly nonlinear due to its nonlinear mechanism and dry friction dominated at low valve speed that could lead to large steady-state displacement errors.

Smooth-switching LPV control for vibration suppression of a flexible airplane wing
Aerospace Science and Technology, 2019In this paper, active vibration suppression of a Blended-Wing-Body flexible airplane wing is studied by utilizing a smooth-switching linear parameter-varying (LPV) dynamic output-feedback control.

LPV Equivalence Transformations
2010In this chapter, we continue the discussion of the LPV behavioral framework by establishing equivalence transformations between the state-space and the input-output representation domains. These equivalence transformations enable the comparison and analysis of LPV model structures and provide essential tools to formulate the identification approach of ...

Robust tracking control of aero-engine rotor speed based on switched LPV model
Aerospace Science and Technology, 2019Thrust control in aero-engines is achieved indirectly due to the lack of thrust sensing technologies. A related variable must be chosen for the control, typically high or low pressure rotor speeds.
