Project Summary

• Drive a platform load with a linear actuator or
  a DC motor
• Microcontroller based feedback control system
• User selects frequency, amplitude, and waveform
  type
• Optional analog input

4
Previous Work

• Linear Actuator
• Power electronics calculations
• Plant model
• System responds with different waveform types
• Bidirectional movement of platform loads

5
Functional Description

• Responds to a platform load via feedback system
• The mode of operation will be determined by the
  user via a keypad on the micro-controller.
• Sinusoidal
• Step
• Triangular
• Flexibility in selecting desired frequency and
  amplitude of the platforms motion
