Aiming at the large error between the frequency of laser inertial navigation signal output and the input frequency and the long response time of the system,a laser inertial navigation signal generator control system based on adaptive parameter tuning was proposed and designed. The structure of the control signal generator control system mainly includes system STC12 LE5 A56 S2 MCU,system DDS chip,system low-pass filter,laser inertia signal amplification circuit,system keyboard,system client display and PC host computer. Based on the system structure frame design,each functional module is designed and implemented. At the same time,according to the advantages of genetic algorithm,the system controller is designed,the workflow of system parameter adjustment is given,and the laser inertial signal generator control is realized. The experimental test results show that the design system improves the shortcomings of the current method,which can output stable waveforms with less distortion,and has the advantages of smaller relative error and better real-time performance.
