Photoelectric Servo System Based On Dsp

Controllers applied for the servo system of photoelectric tracking and measuringequipment presently are almost based on industrial computers with PC/104structure,whichneed lots of electronic boards to compose a set of successful controller.So increased thecubage of a control system,and undermined the reliability.Considering the reasons above,thethesis did some researches for photoelectric tracking servo system,which are based onphotoelectric controlling system of engineering project.Then an photoelectric controllingsystem based on DSP was designed.At first, the thesis gave an introduction about control system of photoelectric controllingsystem. Combined with project requirements, the thesis analysed the basic elements whichcomposed an optical control system.Secondly, according to the project requirement, the thesis did some researches aboutcharacteristics of control system based on DSP and FPGA, summarized some designingmethods of the system based on DSP and FPGA. Also designed the photoelectric controlsystem based on DSP and FPGA,which applied to engineering project, It included schematicand PCB board design.Then the thesis studied some controlling arithmetics which are used widely in the opticalservo system currently. It includes the traditional PID control,introduced other advancedcontrol algorithms, such as complex control, dynamic high-type control, intelligent control.Finally, using platform of project control system, the main program flow chart, thesubprogram flow chart and debugging results have been given, last the thesis explored thesystem’s upgrading space.
