Tracking Control System Based On A Multi-barrel Rocket Launchers In The Dsp Design And Research

In this thesis, a tracking control system is designed and researched experimentally, integrating with a multiple rocket launcher prototype develped, and applying the technology of DSP, CPLD, gray system theory, bus and VHDL synthetically.The tracking control system is used to connect the radar and the multiple rocket launcher servo system. Its functions include target tracking, creating the dummy target trace, adjusting the rocket launcher manually and terminal display. The major research works are as follows: (l)Construct the system frame of "DSP+CPLD", and design the working modes and the missions.The frame takes DSP as the operation control core, processing target tracking, creating the dummy target trace and adjusting the rocket launcher manually; As the assistance, CPLD drives the TFT-LCD to display the parameters. (2)Research the target tracking algorithm based on gray system theory exploringly, and programs the corresponding algorithm procedure. (3)Demonstrate the feasibility of CAN bus and RS232C,RS485 bus used in the system, and establish the communication stipulation. (4)Design the circuit diagrams of the DSP core control board and the TFT-LCD driver board based on the CPLD. (5)According to the different working mode, the corresponging control strategy is programmed with C language and VHDL language. (6)Simulation of target trace prediction and experiment analysises of the dummy target path confirm that the software and hardware are working well, and the target tracking algorithm is tried.The research of tracking control system provide the foundation for transplanting the ballistic trajectory calculation on the board whice will form a embedded and special fire control system, and have the important theoretical value and realistic meanings.
