Motion Synchronization Control for a Large Civil Aircraft’s Hybrid Actuation System Using Fuzzy Logic-Based Control Techniques

Autor: Waheed Ur Rehman, Xingjian Wang, Zeeshan Hameed, Muhammad Yasir Gul

Publikováno v: Mathematics, Vol 11, Iss 7, p 1576 (2023)

The motion synchronization of the hybrid actuation system (composed of a servo-hydraulic actuator and an electro-mechanical actuator) is very important for all applications, especially for civil aircraft. The current research presents a nested-loop c
