Aircraft Stability and Control Augmentation
Aircraft Stability and Control Augmentation Prepared by Assistant Professor Department of Aerospace Engineering Madras Institute Of Technology Chromepet, Chennai Inner-Loop Stability and Control The dynamic Stability characteristics of Aircraft have been improved during the past 50 years using a variety of inner- loop feedback Control systems. Inner loop simply refers to the fact that these systems are represented as the inner loop in a block diagram representation when married with outer-loop autopilot modes such as attitude hold. Inner-loop feedback Control systems has been grouped into three broad categories. Stability Augmentation systems, Control Augmentation systems and fly-by-wire systems. Stability Augmentation systems (SAS). Stability Augmentation systems (SAS) were the first feedback Control system designs intended to improve dynamic Stability characteristics of an Aircraft . It is also referred as dampers, stabilizers, and Stability augmenters.
leading to the control surface or the hydraulic actuator that activated the control surface. • The control authority (percentage of full surface deflection available) of SAS was generally limited to about 10%. • One problem with SAS was the fact that the feedback loop provided a command that opposed pilot control inputs. As a result, the ...
