| Having a stable photoelectric tracking platform system as a background, by using platform integral stability type of gyro stabilized photoelectric platform as the main research object, take the photoelectric platform servo control for gyro stability as the research direction, research based on the gyro stability of stabilized platform and servo control technology, design and development the gyro stable photoelectric platform servo control system which could be able to satisfy the requirement of servo control accuracy index.On the basis of the introduction of gyro stabilized platform, analyzes the mathematical model of controlled object. Analysis of working principle of the circuit on the system stability and carrier platform kinematics analysis. Establish the mathematical model for the third ring structure and feedforward compound control, and discuss its each component part of the transfer function, servo control strategy and the design scheme of the servo controller are presented. From the aspects of system platform configuration, components of the platform structure type selection calculation has carried on the detailed analysis and design, puts forward the system structure design scheme and servo control system hardware and software design. Simulation test results show that the designed azimuth and pitching controller satisfies the requirement of gyro stabilized platform stabilization accuracy.Through this topic research, a comprehensive grasp of the kinematics analysis based on the carrier platform, the theory and servo control method based on gyro stabilized electro-optical platform model. Accumulation the experiment and experience data in the process of development to provide important reference and technical support for future research, which could be able to satisfy the different system requirement of the same type stability control servo system. Its research content has important significance and practical value. |
