Synchronization of brushless DC motors based on LaSalle invariance principle

An adaptive synchronization control method is proposed for the chaotic brushless DC motors based on the LaSalle invariance principle. We show explicitly with numerical proofs that the synchronization error system between the driving and response systems can be asymptotically stable using only a single variable feedback. The present controller is simple in comparison with previous methods. Computer simulation results show that the proposed method is effective.
