This paper brought forward a scheme of optimal controlling of electromotor power system based on SHEPWM technology. The key of the scheme is to get the switch points of the PWM wave by solving a set of nonlinear transcend equation. The authors optimized the switch points selecting of the PWM wave to eliminate selected harmonic. The result of simulation experiment shows that the scheme can effectively eliminate all harmonics and accurately produce selected harmonic or eliminate some harmonic. It can be a valuable reference for power system research.
