Speed Control of a DC Motor

MATLAB GUI for real-time speed control of a DC motor.

The goal of this assignment was to develop a Speed control system for a DC motor. Various control methods were to be employed, both open loop and closed loop. All control methodologies are implemented using MATLAB GUI. The important feature of the system is the auto-calibrate function which provides the capability to calibrate the system at three different levels depending on the desired level of accuracy and recommend whether to use the calibration or not based on the statistics of fit. In closed loop control, on-off, differential, proportional, proportional-plus-differential and proportional-plus-integral-plus-differential are implemented. The system also has a feature to run a diagnostics in order to assess its state of health. A monitoring feature which employs a webcam to monitor the fan by the user is also present. This can be of importance in remote operation of the motor. In addition, the system also provides the feature of data logging both for calibration and for controls.
