Design Of Optoelectronic Platform Servo System And Study Of Control Algorithm

With the gradual improvement of requirement on optoelectronic scrutiny system, optoelectronic tracking system and optoelectronic reconnaissance system, the demand on the stability of optical image is becoming much stricter. The technology of optoelectronic platform which is the combination of several subjects takes mechatronics and automation technology as the principal parts. Since the technology of optoelectronic platform has capacious appliance foreground, the research on it must become a hotspot.Above all, the paper expatiates the hardware circuitry design of optoelectronic platform system. The following parts are expounded in the paper: the design of DSP in servo system and its periphery circuitry as well as the design of communication circuitry and driver circuitry. According to demand of gyro power supply and the characteristics of output signal, it is presented the design circuitry of digital SPWM gyro power supply and improved average modulation cymoscope. The analysis of control mode character of direct current PWM amplifier and the qualitative analysis of electromotor armature current under bipolar mode can be obtained in the thesis.Secondly, the paper presents integrate separate PID algorithm, software flow and experiment result. According to debugging result, the system control precision is obviously ameliorated by two steps: one is to add the anticipatory emendation to improve the amplitude and phase characteristic of the system, the other is to filter of the gathered gyro signal.Finally, aiming at the deficiency of traditional PID algorithm, the paper illustrates the design and simulation of the combined controller of intelligent algorithm and PID algorithm. Compound Axis PID algorithm transfers the traditional single servo control circuit to a system with a main servo control circuitry and a sub-servo control circuitry in order to enhance the control...
