Abstract With certain connection randomness and coupling strength, the permanent magnet synchronous motors in Newman-Watts small-world (NWSW) networks fall into chaotic motion and threaten the secure and stable operation of the drive system. To control the undesirable chaos in complex motor networks, an adaptive controller based on pinning method is first presented. And then, the stability of the controlled system is proved by Lyapunov stability theory and the threshold values of parameter conditions for the onset of stability are obtained. Finally, the simulation results show that the proposed control law is correct and effective. Our research results are helpful to maintain the secure operation of drive system.
