Course Objectives
The objective of this course is to introduce the students the essential knowledge and skills they need to be able to do conceptual and preliminary design of various flight control systems. The course begins with some introductory definitions and classifications followed by aerodynamic considerations in control system design. Then the performance of different control methods is compared. Flight actuators and sensors are introduced including their mathematical modeling. A short review of controller design techniques both in frequency and time domain is made. The linearization of flight vehicle dynamics in the form of transfer functions is addressed. Then we focus on the aerodynamic control system design process of different missiles and aircrafts in some detail. Design of TVC systems is covered separately. The course ends with some miscellaneous topics.
