Abstract

The objective of this project was to go through a real life engineering development cycle, document and justify the design choices, and use background experience in electronic design and control systems to implement the best design possible. The laser driver implemented in this project is designed for the general use of a large variety of diodes in continuous wave mode, much like off the shelf laser drivers. The design goals included improving upon off the shelf laser drivers by decreasing steady state error, setting time, response time, and overshoot. Many different feedback control systems were evaluated, and a modified PID controller was chosen which was designed to overcome the operational behavior of real-life electronics. The system was designed from the ground up, the electronics were simulated in the time domain, the entire system derived into the Laplace Domain and simulated using Matlab/Simulink. A printed circuit board was designed and assembled to verify performance in a real system.
