Precision Laser Tracking For Beam Path Control With PSD Fuzzy Controller

This paper describes tracking optoelectronic system for intelligent and exact controlling of laser beam path depend on position sensor detector (PSD) as feedback backup, in this paper presents a precise control system using a new modern algorithm with a closed-loop system to determine the ideal position and speed of the laser beam path for measuring process, laser beam source is stable and fixed. The feature of the control system proposed in this paper is that the design of the adaptive and repetitive control are independent because each design is based only on the model plant, the system itself defines the situation and angle rotating by a two-hybrid stepper motor with specific mechanisms. Field oriented control (FOC) method is presented to demonstrate effectiveness. For real-time embedded controller. A series of experiments have been conducted to realize better transient response specifications. Part of this paper proposed a nonlinear system predictive model strategy applying based on the local model and some optimization method to solve the control problem for a nonlinear part to obtain accurate results.
