Abstract

The invention discloses an adaptive synchronous control method for a permanent magnetism synchronous motor (PMSM) system and a Rossler system. Firstly, a chaotic motion state equation of a uniform airgap PMSM is established, and a chaotic numerical method is used to analyze the chaotic phenomenon in the PMSM motion; and then, a PMSM system synchronous framework is established, a simple and continuous synchronous controller is designed, adaptive different structure synchronous control on a PMSM master-slave system and a Rossler target system is realized, and generalized synchronization of thePMSM master-slave system and the Rossler target system is proved. The chaotic motion state of the permanent magnetism synchronous motor is firstly obtained, the control law of the chaotic motion system of the permanent magnetism synchronous motor is then deduced based on an adaptive control theory, and finally, different structure synchronous motion control is carried out on chaos of the PMSM system. The control strategy overcomes the shortcomings of poor dynamic performance and low stability in the different structure control between the PMSM system and the Rossler system.

Description

Technical field [0001] The invention relates to the field of permanent magnet synchronous motors, in particular to a permanent magnet synchronous motor system and The system's adaptive synchronization control method. Background technique [0002] The permanent magnetism synchronous motor system (the permanent magnetism synchronous motors, PMSM) is a very complex multi-input multi-output three-dimensional autonomous system. It has time-varying, strong coupling and nonlinear dynamics. Its control problems are very complicated. It is widely used in servo systems, aerospace and other fields, has good dynamic and static performance, and has a simple and reliable structure, which is easy to implement. [0003] The chaotic phenomenon of the PMSM system will threaten the stability of the electric drive system, so it is necessary to eliminate the chaotic characteristics of the motor during operation. Like many systems, the chaotic synchronization control theory of PMSM systems has been de...
