3. 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.

4. Block Diagram

5. 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.

6. Description/Requirements II
Motor System:
Input from DS1103 sent through Transistor or H-Bridge.
Optical Encoder System:
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.

7. 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.

8. 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.
(Not actually setup correctly/completed yet.)
