A new type of tower concentrator is designed,and the utilization rate of light energy by the Beidou positioning and light tracing algorithm is experimentally analyzed.A fuzzy logic PID control algorithm is used to verify the robustness of the system.We improve the field model of the condenser mirror to obtain the distribution pattern of third-order reflected light.Using Tracepro software for optical path simulation,based on the calculated and simulated threshold values,coupled with a two degree of freedom servo,a three-level reflective mirror field is established.In the later stage,we guide students to improve the accuracy of system light tracing and the efficiency of focusing by improving experimental algorithms and designing multi-level mirror fields.The simulation experimental design involves disciplines such as mechanics,optics,circuits,and control,with good functional scalability and high practicality.Exploring the simulation experimental teaching reform path of photoelectric control system design.
