摘要
针对非均匀气隙永磁同步电机系统,首先通过一个仿射变换和时间尺度变换,将电动模型变换成一种简单的数学模型,并验证了在某些参数与工作条件下系统会出现非常复杂的混沌运动或极限环.最后采用Lyapunov稳定性方法,提出了在系统已知参数与未知参数下的自适应控制器,该控制器克服了以往一般自适应控制器中空置率不连续的缺点.仿真结果验证了理论分析的正确性,以及对研究优良的控制方法提供了理论参考.
The permanent magnet synchronous generator（ PMSG） was investigated, Firstly, the model of PMSG in the experiment was transformed into the non - dimensional form via the affine transformation and the single time scale transformation. Then, the mathematical model was built up. The chaotic behaviors or limit cycle phenomena were demonstrated under certain working conditions or the parameters of the model with a certain range of values. A novel adaptive controller was designed based on Lyapunov stability theory, the adaptive controller was proposed in the system with known and unknown parameters. At the same time, the controller overcame the shortcomingsin the past adaptive controller whose vacancy rate was generally not continuous. Simulation results have verified the cor- rectness of theoretical analysis and provided atheoretical basis for the study of fine control methods.
