Title Software design for stabilization platform manipulation subsystem
Abstract
In engineering applications, due to equipment will be disturbed by the movement of the carrier in the working process , will make the equipment with the carrier movement, equipment can not be normal, serious impact on the measurement accuracy of the equipment.For a certain application, the interference of the equipment can be isolated from the stable platform when the equipment can interfere with the environment.This design using a two-stage stabilization platform:the first platform to disturbance of preliminary adjustment, greatly reducing the disturbance amplitude; the secondary platform to further adjust the disturbance, so as to achieve interference isolation.
This paper mainly studies the control technology of the two stage platform.Firstly, the common structure of the stabilization platform is summarized, and their advantages and disadvantages are analyzed.Using a series structure of the secondary platform, and determined the motor and drive selection，the attitude measurement system is composed of the dual axis angle sensor SDI-A626T with full temperature compensation, and real-time attitude information is collected.With the ordinary PC machine as the controller, the PC user interface is designed by VB, and the corresponding VB programming is accomplished.Use VB MSComm control to establish serial connection, using RS-232 connection information transmission.Based on the hardware of the control system, the software system is designed, and the communication between the upper computer and the sensor and the motor driver is finished.For the control strategy of the platform, the PID algorithm is adopted.Finally, the experiments are verified and analyzed.
