Master’s Thesis Defense on Control System Design for Brushless DC Motors

On Monday, December 16, 2019, at 9:00 AM, in the Dijlah Hall of the Electrical Engineering Department, graduate student Qaid Mohsen Ali defended his master’s thesis titled “Design of a Control System for a Brushless DC Motor Based on Sensor Reduction.”

The thesis committee comprised:

• Assoc. Prof. Dr. Abdul Rahim Diab Hammoud (Chair)
• Assoc. Prof. Dr. Ammar Hussein Mutlaq (Member)
• Asst. Prof. Dr. Uday Ali Ahmed (Member)
• Assoc. Prof. Dr. Mohammed Monis Ezzedine Ali (Supervisor and Member)

The thesis proposed a control system using a single current sensor in the DC link. The control system integrates a Sliding Mode Controller (SMC) for speed regulation, characterized by precision and robustness, and a Deadbeat Predictor Controller for current regulation. The proposed system demonstrated high response speed and accuracy, making it easily applicable with a digital signal processor.

The thesis was approved with minor revisions, granting the student a “Pass” grade.
