10. Airship Control Forces and Moments || Airship Nonlinear Dynamic Stability Analysis - 2024

In this video you will see how forces and moments are estimated for one airship fin and then extended it for all four fins in + configuration. The right most fin is at 0 angle and add 90 for next in counterclockwise direction. The fin angle with respect to horizontal plane, theta = [0, 90, 180, 270].

The k3D and eta parameters can be estimated using Grabit tool:

About Course
This course offers a comprehensive guide to analyzing and solving nonlinear equations of motion for airships using Matlab and Simulink. Beginning with the fundamentals of airship dynamics, the course delves into the forces and moments acting on airships, followed by the derivation of nonlinear equations. Participants will learn how to implement these equations in Matlab and develop Simulink block diagrams to simulate airship behavior. The course emphasizes stability analysis, explaining how to linearize nonlinear equations, conduct eigenvalue analysis, and perform real-time stability checks for various flight conditions. Practical considerations such as model validation, control system design, and running simulation scenarios are also covered. Advanced topics include handling higher-order nonlinear effects and optimizing airship design for improved stability and performance. By the end of the course, learners will have a robust understanding of airship dynamics and the tools to ensure stable flight in various conditions.
