| The induction motor driving technologies are being improved quickly and new control strategies are developed and applied for different applications. The advanced ac motor driving systems are of high performances and competent to the dc motor driving systems. Variable-frequency speed regulation is a tiptop way about speed regulation. The computer simulation of the electric drive system is one of the quite important means in the science research using modern scientific means.It mainly introduced the development of AC regulating speed system and the basis elements of SPWM(SVPWM) control and how to use SIMULINK in software MATLAB and establishing asynchronous motor's math model. The emphases are simulation about every part of the system and SPWM (SVPWM) control system, and analyzed and researched power factor of induction motor the relation between the self-parameter andΔω. Through many of the simulation test, system's capability was researched about steady condition and dynamic and diversified circs. It is base for more development and using of new experimental installation. |
