Lecture notes from the introduction lecture to control systems in aerospace. Covers: control systems; and types of control systems.

This revision sheet covers the key points involved in the course. It outlines the derivations involved in the calculations around the phugoid mode and SPPO, as well as angle notation, and an overview of each mode.

Notes from lecture 8, a summary lecture covering the key points of each previous lectures - namely: Notation; Types of aerodynamic effects; review of modes; equations for longitudinal modes; and the equations for the lateral/directional modes.

Notes from lecture 7 - covering: Dutch Roll mode; dutch roll mode derivatives; damping derivatives; vertical tail contribution; and spiral mode.

Notes from lecture 6 on roll and dutch roll modes - covering: roll mode; roll damping due to wing; roll damping due to VTP; roll control; aileron control derivative; other means of roll control; conditions for low aileron effectiveness; directional derivatives; side force equation; yawing moment coefficient; lateral derivative; wing dihedral angle; wing sweep angle; and mechanics of a sideslip.

Notes from lecture 5 on lateral/directional modes - covering: lateral/directional aerodynamic derivatives; types of aerodynamic effects; lateral/directional modes; roll mode; dutch roll mode; and spiral mode.

Notes taken from lecture 4 on lateral and directional flight - covering: lateral/directional motion; aircraft orientation angles; definition of these angles; directional vs longitudinal flight; lateral disturbance angles; aerodynamic effects with non-dimensional derivatives; and governing equations.

Notes taken from lecture 3 on the longitudinal modes - covering: longitudinal dynamics equations; the linearisation of these equations; summary of the longitudinal modes; forced response; first order systems; second order systems; characteristic parameters for unit step response of a second order system; and practical analysis of a second order system response.
