"Working on the design of the Lunar Module digital autopilot was the highlight of my career as an engineer. When Neil Armstrong stepped off the LM (Lunar Module) onto the moon's surface, every engineer who contributed to the Apollo program felt a sense of pride and accomplishment. We had succeeded in our goal. We had developed technology that never existed before, and through hard work and meticulous attention to detail, we had created a system that worked flawlessly." -Richard J. Gran, The Apollo 11 Moon Landing: Spacecraft Design Then and Now.

Use the Control System Toolbox™ and Simulink® Control Design™ to interact with Simulink to design a digital pitch control for the aircraft. In this example, we will design the controller to permit the aircraft to operate at a high angle of attack with minimal pilot workload.

Questo esempio mostra come modellare il movimento a sei gradi di libertà in Simulink®. È possibile passare dall'uso degli angoli di Eulero a quello dei quaternioni per modellare le equazioni del moto, utilizzando il menu contestuale del blocco Variant Subsystem "Variant > Override using" (Variante > Sovrascrivi utilizzando).

Controllo del volo modello per il moto longitudinale di un aereo utilizzando approssimazioni lineari del primo ordine.

Questo esempio mostra come utilizzare un filtro di Kalman esteso con il blocco MATLAB® Function in Simulink® per stimare la posizione di un aereo a partire dalle misurazioni del radar. L'implementazione del filtro si trova nel blocco MATLAB Function, il cui contenuto è memorizzato nel modello stesso di Simulink.

Generate a movie with 64 frames and a frame size of 64 by 64 pixels (at 10 frames per second). The movie contains a simulation of a moving target that is moving through a structured background that is itself moving. A jitter motion caused by random vibration is also generated (in a Simulink® model called "aero_vibrati") and the jitter motion is added into the overall sensor motion. Finally, the image is blurred through a Gaussian optical point spread function.

Model a conceptual air traffic control (ATC) radar simulation based on the radar range equation.

Use the model of the missile airframe presented in a number of published papers on the use of advanced control methods applied to missile autopilot design. See [1], [2], and [3]. The model represents a tail-controlled missile traveling between Mach 2 and Mach 4, at altitudes ranging between 10,000 ft (3,050 m) and 60,000 ft (18,290 m), with typical angles of attack ranging between +/- 20 degrees.
