摘　　要：基于混沌非线性控制理论,建立了永磁调速器物理模型和二阶自治数学模型。使用C-C方法重构相空间,准确地求得相空间嵌入维、延时时间,给出了永磁电机混沌系统最大Lyapunov指数的计算方法。提出了采用混沌自适应法控制永磁电机系统的思想,以Duffing系统为跟踪对象,设计了自适应控制器系统。通过SIMULINK建模仿真发现,永磁电机动力学方程稳态下和参数变化时,系统最大Lyapunov指数分别为0.655和0.814。参数变化时,混沌吸引子迅速进入稳定状态,具有良好抗扰性,该研究方法可为永磁电机控制系统设计提供理论依据。Based on chaotic nonlinear control theory,the physical model and the second-order autonomous mathematical model for permanent magnetic driver( PMD) were established. Using the C-C method to reconstruct the phase space,embedding dimension and delay time was obtained accurately and the calculation method of maximum Lyapunov index was given for chaotic PMD system. The thought of adopting chaos self-adaptive method was put forward to control PMD system,taking the duffing system as tracking object while the adaptive controller system was designed. By SIMULINK modeling simulation,maximum Lyapunov indexes were 0. 655 and 0. 814,when dynamics equation of PMD was under steady state and parameter changing. And chaotic attractor was into a stable state rapidly after parameter changing,having a good resistance to interference. The works provide a theoretical basis for control system design of PMD.
