Goals
Decrease the learning curve for the use of the dSPACE
DS1103 Workstation by future students by:



Writing a Tutorial for use of the new DS1103
Workstation.
Designing one or more controllers to control the speed
of a DC motor.
Implementing the controller design(s) using the
DS1103 Workstation.
Block Diagram
Description/Requirements I

ControlDesk software:
Installed on PC.
 Monitoring, Downloading, maybe Changing (Speed)
Inputs.


Controller:
One or more designs.
 Simulink and RTI blocks.
 PWM Output through DS1103 PWM or D/A Output.

Description/Requirements II

Motor System:


Optical Encoder System:


Input from DS1103 sent through Transistor or HBridge.
May have additional components between output of
optical encoder and DS1103 A/D Input.
CLP1103 LED/Connector Panel:

A/D, D/A, PWM I/O to/from DS1103.
Current Controller Requirements

The DC motor speed controller
designed/simulated using Simulink and
dSPACE blocksets, Matlab-to-DSP interface
libraries, the Real-Time Interface to Simulink,
and Real-Time Workshop.

Overshoot less than or equal to 5%.
Rise time less than or equal to 20 ms.
Steady-state error shall be less than or equal to
5 RPM.


Current Progress



Reading/Reviewing of several hundred pages of
guides/manuals. (Listed later.)
Detecting the DS1103 Board using ControlDesk.
Beginning work on A/D Converter input, Simulink
gain block, and D/A Converter output, to obtain quick
overview of simple interactions between DS1103
Board, ControlDesk, and the analog world.
