Abstract

Disclosed is a sliding-mode synchronization control method of a double-permanent-magnet synchronous motor chaos system. The sliding-mode synchronization control method includes: establishing a chaos model of a permanent magnet synchronous motor system as shown in the form, and initializing system state and relevant control parameters; at each sampling instant, calculating synchronization errors, sliding model surfaces and a first-order derivative of the permanent magnetic synchronous motor chaos system; designing a robust controller by adopting an active sliding-mode control method and finally realizing quick synchronization of the chaos state of the double-permanent-magnet synchronous motor chaos system with two different initial conditions and uncertain parameters.

Description

technical field [0001] The invention relates to a sliding mode synchronous control method for a chaotic system of double permanent magnet synchronous motors, in particular to a synchronous control method for a chaotic system of permanent magnet synchronous motors with two different initial conditions and uncertain parameters. Background technique [0002] Permanent magnet synchronous motor (PMSM) is a typical multivariable, strongly coupled nonlinear system, which has been widely used in high-performance systems such as robots, aerospace vehicles and servo turntable control. However, research in recent years has shown that permanent magnet synchronous motors will exhibit chaotic characteristics under certain conditions. The existence of chaotic behavior will generate irregular current noise, which seriously affects the stable operation of the system and causes inconvenience to the application of PMSM. However, chaotic motion in permanent magnet synchronous motors is not alwa...
