CPCI Bus Technology-based Photoelectric Tracking Control System Design

This paper studies the ship-carried photoelectric tracking servo control system algorithms and software design. The hardware platform provides the foundation for the digital control algorithm. The main goal is meeting tracking high-speed target requirements, improving the performances of the servo system, tracking acceleration and dynamic performance and optimized design system, improving system performance and reliability and maintainability. Commonly control algorithms, and topics of the actual situation, the subject uses the appropriate method to complete the requirements of the system.When tracking and the target for the far zone and no continuous amount of distance. The servo system uses the second part of the digital adaptive control technology. When the goals for the near zone and there is a continuous amount of distance, the servo system uses regenerative feed back plus composite control. This software by the PID algorithm, the calculated amount of the digital error correction amounted by the D/A converter outputs an analog to the servo electronics box, complete the closed-loop control of the servo system.Tunings process is divided into three parts:the acceleration segment, deceleration segment, constant speed segment. The devices in the case of their work complete the start action, acceleration, deceleration, brake action. Therefore, the speed must be closed-loop control. The actual value of the number of degrees of the system’s real-time detection of motor, comparison, according to the error orientation were used in control, PD control and BangBang control to do with the current setting.Eventually completed by servo control system optical tracking system the following functions:acquisition tracking sea and air targets ranging to the fire power system provide real-time target firing. Provide independent observation, search, acquisition, tracking, and real-time target data.
