The Challenge of Control System Development

Growing Requirements

As global air traffic increases, so do the requirements on

the fuel consumption, noise emission, flight range and

economic efficiency of aircraft. On top of all that, aero-

space developers and manufacturers must adhere to very

high safety standards and guidelines.

To rise to these challenges, they are pushing forward with

development work in many different fields. dSPACE systems

play a vital role throughout the entire development process

for electronic control systems, giving aerospace engineers

the tools they need to set up high-performance develop-ment environments.

optimized mechatronic control system development.

dSPACE supports all stages of development. The advan-

tages are threefold: a considerable saving in time and

cost, greatly enhanced software quality, and more effi-

cient interaction between manufacturer and supplier.

This brochure is designed to answer your questions con-

cerning the dSPACE development environment. Whether

you use our tools throughout the entire process or at

individual stages, you can rely on dSPACE to make a realimpact on the efficiency of your development cycle.

8Use Scenarios

Typical Use Scenarios for dSPACE Products

Aircraft Systems

Electric and electronic systems play a major role in

modern aircraft, and aircraft support and flight systems

are increasingly controlled and monitored by electronics.

At the same time, environmental legislation is forcing

companies to reduce aircraft weight and lower overall

fuel consumption. These trends affect a wide range of

aircraft systems, such as flight control systems (control

surfaces and cockpit controls), navigation systems, health

and usage monitoring systems (HUMS), and aircraft net-

works (AFDX, MIL-STD-1553, ARINC 429, etc.).

Use Case: Actuator Tests on an Iron Bird

This iron bird can easily run through a wide range of

flight situations and simulate a large number of faultsin the hydraulics, electrics, flight control system, and

actuators. The faults that can be simulated include

pressure changes in the hydraulics and component

failures.

Airframe

Modern airframes, including components such as control

surfaces, landing flaps, slats, landing gear, etc., contain

countless electric components. For example, control sur-

faces are activated by electric or electro-hydrostatic actua-

tors instead of hydraulic actuators. Iron birds aircraft

test benches are vital tools in developing these systems,

as they automatically and realistically reproduce any con-

ceivable flight situation. dSPACE systems play a central

role here, calculating models for real-time flight maneuver

simulation.

Each of the DS1005 boards has its own task to per-

form, such as calculations for the real-time simulationof flight maneuvers, the hydraulic system or control

surfaces, or autopilot functionalities like automatic

landings. One special strength of the dSPACE com-

ponents is their flexibility, which makes it possible to

adapt the test facility to new actuator concepts and

aircraft types with a minimum of effort.

Unmanned Aerial Vehicles

Unmanned aerial vehicles (UAVs) are being introduced in

many different areas, including surveillance, security, crop

monitoring, law enforcement, and even package delivery.

One particular challenge is autonomous flight in gen-

eral airspace shared with normal manned commercial

aircraft. To meet this challenge, high-performance envi-

ronment recognition and intelligent on-board real-time

Use Case: Researching Extreme Flight Situations

In this example, a UAV is used to study flight situa-

tions that would be too dangerous and too expensive

with a real aircraft. The ground-based flight control

system is implemented as a dSPACE system, which

provides the high performance required by the com-

plex real-time computations during test flights with

the UAV. The system processes the measurementvalues collected by the UAV and also the flight com-

mands in real time, supports the generation of data

for flight displays, and records test data for post-flight

analysis. The dSPACE system communicates with

the UAV over a high-bandwidth telemetry link. The

ground stations computer systems consist of two

DS1005 Processor Boards and several connected

workstations for display generation and data log-

Use Scenarios

ging. One CPU in the dSPACE system handles the

pilot inputs, manages the telemetry stream to and

from the aircraft, and calibrates and processes data

to drive real-time displays. The second dSPACE CPU

is dedicated to research control algorithms which are

invoked during the flight under both nominal and

failed vehicle configurations. These control algorithmsare routinely swapped out for different flight experi-

ments, and implement code developed and proto-

typed in Simulink using a simulation model for the

vehicle. The use of a secondary CPU for this code not

only provides a high level of computing power but

also allows the master CPU to monitor and isolate any

software faults, including code lockup, segmentation

faults, or unbounded behavior.

aircraft control software are absolute necessities. dSPACE

systems are perfectly suited for developing such systems:

for intricate tasks such as processing sensor data in real

time during actual flight, or testing the onboard systems

in virtual laboratory test flights, dSPACE prototyping and

HIL test systems speed up development, and help cut

costs and improve software quality and reliability.

Space Flight

When developing space flight technology, aerospace

engineers are constantly striving to push the limits of

what is technically possible. At the same time, system

reliability is their top priority, since an error in space can

result in expensive losses and delays, and have fatal con-

sequences. So it is imperative for system engineers to get

Use Case: Testing a Navigation System

In this use case, the dSPACE systems task is to simu-

late the atmospheric reentry of a rocket nose cone.

The dSPACE system allows complete preflight simula-

tion of the flight sequence after reentry, including

navigation signals, in order to test the interactionbetween all components. In the first test step, the

experiment setup consists solely of the dSPACE system

and the navigation computer. The actual navigation

devices inertial measurement unit (IMU), GPS, star

tracker are not connected at this stage, so their sig-

nals are all simulated by the dSPACE system. This test

phase validates and optimizes the basic functionality

of the navigation software. In the second step, the

it right the first time. Thats where dSPACE systems can

help. The typical applications of dSPACE equipment in the

field of space flight are in developing navigation systems,

satellite position controls, and propulsion (combustion

control, thrust control, vibration damping).

GPS and a GPS signal generator are connected

so that GPS navigation can be tested. The third step

(see diagram above) then connects the IMU, which

is mounted on an ACUTRONIC rotation table to simu-

late different craft movements. The integrated startracker receives a simulated map of the stars from

a Jenoptik sky simulator.

One special challenge handled by the dSPACE system

is to synchronize the measurement signals with the

navigation computers internal clock. This is particular

important because of the high velocities of the nose

cone during reentry, when time delays in GPS mea-

surements seriously affect the navigation solution.
