Permanent Magnet Synchronous Motor model can exhibit a variety of chaotic phenomena under some choices of system parameters and external input. Based on the property of passive system, the essential conditions were studied, by which Permanent Magnet Synchronous Motor chaotic system could be equivalent to passive system. Using Lyapunov stability theory, the convergence condition deciding the system's characters was discussed. In the convergence condition area, the equivalent passive system could be globally asymptotically stabilized by smooth state feedback. 相似文献

The new chaos control method presented in this paper is useful for taking advantage of chaos. Based on sliding mode control
theory, this paper provides a switching manifold controlling strategy of chaotic system, and also gives a kind of adaptive
parameters estimated method to estimate the unknown systems' parameters by which chaotic dynamical system can be synchronized.
Taking the Lorenz system as example, and with the help of this controlling strategy, we can synchronize chaotic systems with
unknown parameters and different initial conditions.
