Anwendungen für die Luft- und Raumfahrt

Modellierung von Luft- und Raumfahrtsystemen mithilfe von Simulink^® und Aerospace Blockset™-Software

Simulink ermöglicht es Ihnen, eine Vielzahl von Luft- und Raumfahrtsystemen zu modellieren und simulieren. Die nachfolgenden Beispielmodelle veranschaulichen Anwendungen in der Luft- und Raumfahrt.

Wenn Sie Luft- und Raumfahrtsysteme in der Simulink-Umgebung modellieren, sollten Sie Aerospace Blockset verwenden. Aerospace Blockset erweitert Simulink und ermöglicht Ihnen die Modellierung, Simulation und Analyse der Dynamik von Luft- und Raumfahrzeugen. Sie können die Fahrzeugdynamik einbeziehen, Modelle der Flugumgebung überprüfen, das Verhalten des Piloten modellieren und Ihr Modell dann mit dem FlightGear-Flugsimulator verbinden, um die Simulationsergebnisse zu visualisieren.

Developing the Apollo Lunar Module Digital Autopilot

"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.

Designing a High Angle of Attack Pitch Mode Control

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.

Radar Tracking Using MATLAB Function Blocks

Create a Kalman filter that estimates the position of an aircraft by using a MATLAB Function block. After estimating the position, the model calls an external MATLAB® function to plot the tracking data.

Optical Sensor Image Generation

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.

Design a Guidance System in MATLAB and Simulink

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.
