With the change of modern development of military scientific technology, it can using new technology, improve or renovate control system to greatly enhance the positioning and tracking accuracy of multiple rockets, in order to adapt nowadays’ war , my thesis base on a small launch pad , mostly study the servo control arithmetic , using the advanced control theoretics, deeply research the neural PID .Mathematical model of PMSM is analyzed , research the SVPWM technology, particularly make out the method and the process to generate SVPWM make use of DSP . Base on PMSM vector control principle ,using Matlab/Simulink to create simulation model, compared the PID、single neural PID、RBF neural PID and BP neural PID , and analyse the four control arithmetic , to table a proposal to improve the BP network . Then ,using TMS320F2812 DSP ,and adopt modularization idea to design the hardware ,mainly communications、power supply、power switch、measure block and so on; Base on main, using modularization idea to design the subprograms .Finally , using CCS write the improved BP neural PID for position controller, made some experiments on the small launch pad by SEED-DPS2812 , and the experiments proved that the position controller has good fast response and adaptability , identical to the former simulation , and lays the foundation for the following research.
