Stability and Control of Aircraft Systems [PDF ebook] 
Introduction to Classical Feedback Control

In the current climate of increasing complexity and functional
integration in all areas of engineering and technology, stability
and control are becoming essential ingredients of engineering
knowledge. Many of today’s products contain multiple
engineering technologies, and what were once simple mechanical,
hydraulic or pneumatic products now contain integrated electronics
and sensors. Control theory reduces these widely varied technical
components into their important dynamic characteristics, expressed
as transfer functions, from which the subtleties of dynamic
behaviours can be analyzed and understood.

Stability and Control of Aircraft Systems is an
easy-to-read and understand text that describes control theory
using minimal mathematics. It focuses on simple rules, tools and
methods for the analysis and testing of feedback control systems
using real systems engineering design and development examples.

* Clarifies the design and development of feedback control
systems

* Communicates the theory in an accessible manner that does not
require the reader to have a strong mathematical background

* Illustrated throughout with figures and tables

Stability and Control of Aircraft Systems provides both
the seasoned engineer and the graduate with the know-how necessary
to minimize problems with fielded systems in the area of
operational performance.
