The Research Of Fuzzy Control On Asynchronous Motors Speed Regulation

In recent years, international energy shortage and exhausts brought huge loss to the national economy. The paper mainly studies the application of fuzzy control to asynchronous motor by variable voltage speed regulation and vector control system, which make asynchronous motor energy-efficient. Electric drive system of intelligent control is a hot research topic, and fuzzy control is an important research branch, are gaining increasing attention of researchers. It isn't necessary to establish accurate mathematic model of controlled device, and has good robustness and nonlinearity. The system of variable voltage speed regulation and vector control has many fine attributes for the development and application, at the same time, it exists some problems, such as the complex structure of the system, nonlinear and the changing of motor parameter affect system performance. Through inspection much literature, the paper analyzes a condition of intelligent control in the field of modern electric drive. The paper mainly studies the application of fuzzy control to asynchronous motor by variable voltage speed regulation and vector control system through...
