Attitude Control in the HL-20 Autopilot - SISO Design

This is Part 3 of the example series on design and tuning of the flight control system for

the HL-20 vehicle. This part shows how to tune a classic SISO architecture for controlling

the roll, pitch, and yaw of the vehicle.

Background

This example uses the HL-20 model adapted from “NASA HL-20 Lifting Body Airframe”

(Aerospace Blockset), see Part 1 of the series (“Trimming and Linearization of the HL-20

Airframe” (Control System Toolbox)) for details. The autopilot controlling the attitude of

the aircraft consists of three inner loops and three outer loops.
