The research of the influence of gyro motor speed stability on the north-seeking result is studied in order to improve the gyro north-finding precision. The paper introduces a two-phase brushless DC gyro motor control system based on TMS320LF2407A. First it expounds the two-phase brushless DC motor's working principle. Then through the design of the hardware and software system, the two-phase brushless...
This article develops a design processes based on combined machine controller and C2000 DSP through combining Matlab/Simulink simulation Links and Targets/C2000 development environment together. Meanwhile it elaborates a hardware circuit module and software controller design. This controller could automatically and intelligently realize united power machines combination, power transformation and the...
Because the SPIHT algorithm used too much memory and its encoding speed was slow on the DSP hardware system, an improved SPIHT algorithm was put forward. It adapted better to the feature of DSP, and it improved efficiency and speed. So, the run time was shortened and the requirement of real time compress was realized. To solve the problem of the SPIHT being sensitive to single bit error, the paper...
