Abstract

Disclosed is a finite time synchronous control method of double permanent magnet synchronous motor chaotic systems. The method includes that a chaotic model of a permanent magnet synchronous motor system is established, and system state and relevant control parameters are initialized; at every sampling instant, synchronous errors, rapid nonsingular terminal sliding mode surfaces and first-order derivatives of principal and subordinate chaotic systems of a permanent magnet synchronous motor are calculated; according to the synchronous errors, the rapid nonsingular terminal sliding mode surfaces and the first-order derivatives, a synchronous controller of the double permanent magnet synchronous motor chaotic systems is designed, the problem of buffeting during sliding-mode control can be solved, and chaotic states of the principal and subordinate chaotic systems can be rapidly synchronized.

Description

technical field [0001] The invention relates to a finite time synchronous control method for a chaotic system of double permanent magnet synchronous motors, in particular to a finite time synchronous control method for a chaotic system of double 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 ...
