SELF-ADAPTIVE AIR-PATH HEALTH MANAGEMENT FOR A HEAVY DUTY-DIESEL ENGINE

open access: yesInternational Journal of Prognostics and Health Management, 2023
This paper presents the air-path health management strategy with the ability to estimate the mass-flows and mitigate (adapt to) the air-path faults in the exhaust system of a heavy-duty diesel combustion engine equipped with a twin-scroll turbine.

Design and Analysis of a Linear Hybrid Excitation Flux-Switching Generator for Direct Drive Wave Energy Converters

open access: yesAdvances in Mechanical Engineering, 2013
Linear generators have the advantage of a simple structure of the secondary, which is suitable for the application of wave energy conversion. Based on the vernier hybrid machines (VHMs), widely used for direct drive wave energy converters, this paper ...

Rotational motion control of a spacecraft

open access: yesIEEE Transactions on Automatic Control, 2003
The paper adopts the energy shaping method to control of rotational motion. A global representation of the rigid body motion is given in the canonical form by a quaternion and its conjugate momenta. A general method for motion control on a cotangent bundle to the 3-sphere is suggested.

Manoeuvring and Motion Control of a Hydrofoil

open access: yesIFAC Proceedings Volumes, 1987
Computer-aided design techniques are described and demonstrated in studies associated with the regulation of pitch, roll, heave and yaw of a 31 m surface piercing hydrofoil. The procedures outlined are effected by way of a comprehensive suite of software for control system data processing which is employed in the transformation of the basic model into ...
