The Modeling And Simulation Of Vector-Control System For SPWM Variable Frequency Control

This paper mainly studies the modeling and the simulation about vector control system of the SPWM variable frequency control, 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. Along with developing digital computer, the big difficulty index math-physics count become easily now. As a result of simulation ground on math model have upper precision, and model facile be conversion, the many of studies are the math simulation now. Because the system simulation have many excellence, suts as can be controled, has not destroy the equipment, safety, the outside condition cannot limit it, and it can complex analyse and compare the complex matter and the policy and the project, and optimize and confirm theirs parameter through build lifelike math simulation and iterative simulation test at the computer. The system simulation cannot lake yet especially for new research of the control decision-making and count-method. It offer credible gist for science decision-making.It mainly introduced the development of AC regulating speed system and the basis idea of Vector control and how to use SIMULINK in software MATLAB and establishing asynchronism's math model. The emphases are simulation about every part of the system and vector control system. Through many of the simulation test, system's capability was researched about steady condition and dynamic and diversified circs. It is base for more empoldering and usinging of new experimental installation...
