| 摘 要： | 对无轴承永磁同步电动机提出非线性L2鲁棒控制。在考虑负载、电机电阻以及转子离心力等各种干扰的情况下建立了电机的非线性数学模型,并且通过构造适当的存储函数推导出用于描述L2鲁棒控制器的四个控制律,最后利用仿真测试转速和转子悬浮的抗干扰性能证实了控制律能满足干扰抑制和系统的渐进稳定。

| Abstract: | Nonlinear L2 robust control for bearingless permanent magnet synchronous motors (BPMSM) was presented.First,nonlinear mathematical model of motors was established in the case of a variety of disturbances under consideration,for example,load,motor resistance and centrifugal force of rotor.Furthermore,four theorems used in describing L2 robust controller were derived by constructing proper storage functions.Final,these L2 robust control laws which met disturbance restraint and asymptotical stability were proved by means of simulation test of disturbance-rejection performance of speed and rotor suspension. |
