Abstract

The invention provides a Chua system-based brushless direct current motor chaos controller and a design method thereof. The controller comprises a control unit, a coordinate transformation unit, a VPWM inverter unit, a brushless DC motor, a rotating speed detection unit and a voltage detection unit. A drive system and a response system achieve the targets of synchronization and synchronous controller design through chaos analyses of the brushless direct current motor. The Chua system-based brushless direct current motor chaos controller has the advantages of an accurate control objective and a high response speed.

Description

technical field [0001] The invention belongs to the technical field of chaos controllers for motor systems, and in particular relates to a chaos controller for a brushless DC motor based on a Chua system and a design method thereof. Background technique [0002] In recent years, the research on chaotic system theory has become more and more mature, and the chaos control in motors has also become one of the hot spots of research. The research on the system model with certain parameters of brushless dc motor and some deformed new chaotic systems based on the famous Lorenz system, such as chen system and liu system, has certain reference value. Compared with the general chaotic system, the Chua system has more complicated dynamic behavior, and the randomness and unpredictability of the system are stronger. For brushless DC motors, it has been widely used in drive devices and servo systems because it not only has the advantages of simple structure and reliable operation of AC m...
