  1. dSPACE DS1103 Control Workstation Tutorial and DC Motor Speed Control By: Annemarie Thomas Advisor: Dr. Winfred Anakwa December 9, 2008

  2. Outline • Goals • Project Description • Block Diagram, Functional Description, Requirements • Current Progress • References • Schedule for Completion • Equipment

  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.)

  12. Schedule for Completion * Spring Break is March 14 – March 22, 2009

  13. Equipment I • Workstation • $14,000 dSPACE DS1103 system consisting of: • DS1103 Board. • Expansion Box. • CLP1103 PPC Connector and LED Panel. • ControlDesk Version 3.2.2/Other dSPACE provided Software Applications. • PC dedicated to the workstation containing other software applications required (Matlab/Simulink Version R2008a and libraries).
