Nonlinear Feedback Anti-control of Chaos in Permanent Magnet Synchronous Motor

摘要

To take advantage of chaos in permanent magnet synchronous motor system,the permanent magnet synchronous motor systems with smooth and non-smooth air-gap models are established.In these systems,through applying a nonlinear feedback controller,the original stable permanent magnet synchronous motor systems show chaotic behavior,that is,anti-control of chaos is achieved.It can obtain a new chaotic attractor with the completely different topology.Numerical simulation shows that the control method is effective and feasible.It can provide the theoretical basis of chaotic motion.
