Servoactuators are closed-loop actuation devices that integrate a servo valve or servo motor with positional feedback — typically via LVDT, resolver, or encoder — to deliver precise, command-following motion control for flight control surfaces, thrust vectoring, landing gear, and secondary airframe functions, encompassing both hydraulic and electric servo variants along with associated control electronics and feedback signal conditioning.
