摘　　要：在张波等提出的混沌模型的基础上，采用Backstepping方法对永磁同步电动机的混沌运动进行控制．该方法是建立在Lyapunov稳定性的基础上的，选择适当的控制法则，将稳定或不稳定的平衡点引导到稳定的平衡点上来．数值仿真表明，当t→∞时，控制量ud和uq是有界的且是收敛的，说明该控制量是有效的．Backstepping based chaotic control for permanent-magnet synchronous motor （PMSM） is implemented on the basis of the chaotic model presented by Zhang Bo. Such a control method can make the new stable equilibrium points interlaced by stable or unstable equilibrium points using a suitable control law based on the Lyapunov stability theory. The results of numerical simulation has shown that when the parameter of time, t, tends to infinity, the control values of ud and uq are bounded and constringent, from which it can be concluded that such control values are effective.
