DC Motor Position Control

In this lab students start by studying the theory of quantitative PD control design along with necessary equations. Then students will implement a controller on a DC motor and obtain and analyze response data. Finally, students will asses the steady-state error and answer several short answer questions and calculations.

This is lab 2 of 16 in the course, Control System Design and Analysis.


After completing this lab, students will be able to:
  1. Design PD control parameters to mee position control specifications
  2. Analyze the response of a position controller
  3. Assess the steady-state error of a position controller
