Abstract—In a Laser Tracking System (LTS) the control objective is for a laser beam to track targets. This is done based on the returning laser beam, as measured by a four-quadrant photodetector is required to be centered in the surface of Quad Detector (QD). This brief shows that Fuzzy logic controllers (FLC) can outperform classic controllers in such applications. The advantages of utilizing a Proportional–Integral–Derivative (PID) like fuzzy controllers to improve the control performance for a system with noise and a relatively long time delays is confirmed by simulation results. To have a complete designation and tracking system, an experimental characterization is presented including current verses voltage curves, output optical power verses drive current curves, temperature dependence of wavelength is illustrated and a laser modulation with a specific PRF code was developed.
