| Abstract: | After being analyzed and improved,a new SPWM algorithm based on symmetric regular sampling is presented.With the timing program and the program-delay analysis,three-phase SPWM waveforms output from single chip unit C51.The antenna position and the position of the servo motor rotor are supplied by the magnetism revolving encoder.And the mobile antenna servo system is controlled efficiently.The scheme is proved to be simple and feasible by the experimental result. |
