Modelling and Control of Mini-Flying Machines es una exposición de modelos desarrollados para ayudar en el control de movimiento de los diversos tipos de mini-aviones:
- Planar vertical de despegue y aterrizaje de las aeronaves;

- Helicópteros;

- Quadrotor mini-helicópteros;

- Otras aeronaves de ala fija;

- Dirigibles.

Para cada uno de estos se propugna:

- Modelos detallados derivados de los métodos de Euler-Lagrange;

- Las estrategias de control y las propiedades de convergencia adecuado no lineal;

- Comparaciones experimentales en tiempo real del rendimiento de los algoritmos de control;

- Revisión de los principales sensores, en pensión electrónica, la arquitectura en tiempo real y sistemas de comunicación para el control de la máquina mini-vuelo, incluyendo la discusión de su desempeño;

- Explicación del uso del filtro de Kalman se detalla a volar la localización de la máquina.

Para los investigadores y estudiantes en el control no lineal y sus aplicaciones Modelización y Control de Máquinas Mini-Flying proporciona información valiosa a la aplicación de técnicas no lineales en tiempo real en un área siempre un reto.
