Abstract

A description is given of the Smart Actuator, that is, an actuator that contains its own electronics. The electronics package forms an integral part of the actuator, coexisting with the mechanical and hydraulic hardware in the same hostile environment. The goal of this effort was to design electronics for high temperature using the requirements of the F/A-18 Aileron (135°C). The electronics provide transparent control of the aileron with closed-loop operation, fault detection/isolation, redundancy management, and fail-op protection. Dual-channel fault isolation provides automatic shut-down of a channel when a fault is detected, and a damped mode of operation when a second channel failure is detected
