Abstract

The embodiment of the invention discloses a permanent magnet synchronous motor control device and method based on a variable-order fractional-order sliding mold, and relates to the technical field of alternating current servo motor control. The problem of performance reduction in a fixed-order fractional-order sliding mold control method can be solved, and the following precision is improved. According to the permanent magnet synchronous motor control device and method based on the variable-order fractional-order sliding mold, a fuzzy variable-order controller and a variable-order fractional-order sliding mold surface are constructed, and a variable-order fractional-order sliding mold rotary speed controller is designed to conduct rotary speed regulation. The permanent magnet synchronous motor control device and method based on the variable-order fractional-order sliding mold are suitable for operational control of a permanent magnet synchronous motor.

Description

technical field [0001] The invention relates to the technical field of AC servo motor control, in particular to a permanent magnet synchronous motor control device and method based on variable-order fractional-order sliding mode. Background technique [0002] The permanent magnet synchronous motor has the advantages of compact structure, high power density, high energy conversion efficiency, wide speed range, light weight, etc. It is superior to many other types of motors in terms of energy saving, emission reduction, environmental protection and low carbon, so it is emphasizing low carbon Under the environment of development, it is widely used in industrial production and various energy systems based on military / civilian technology. [0003] However, permanent magnet synchronous motors also have disadvantages such as the maximum torque being limited by the demagnetization of permanent magnets, the motor structure is complex, and the system control is difficult. In particula...
