基于特征模型的永磁同步电机非线性黄金分割自适应控制

NONLINEAR GOLDEN-SECTION ADAPTIVE CONTROL OF PERMANENT MAGNET SYNCHRONOUS

针对永磁同步电机系统复杂难以准确建模和控制器设计不易问题,文章采用id=0的矢量控制策略,建立了永磁同步电机的二阶特征模型,经验证其动态特性能真实逼近实际模型.基于该特征模型设计了一个带有安排过渡过程且以非线性黄金分割自适应控制器为主的控制方案.通过Simulink仿真实现了该控制方案下可调参数的整定以及方案可行性的验证.最后在实际平台上验证了控制方案的有效性,实验结果表明该方案能够实现永磁同步电机的高精度控制.

Owing to two problems of permanent magnet synchronous motor （PMSM）, one of which is difficult to model the PMSM, the other one is that controller design is hard. Therefore, this technical note utilizes the vector control strategy with id = 0, and develops the second order characteristic model of PMSM, as well as validates the dynamic trait to conform to the real one. Based on the characteristic model, we propose a control scheme including a process of transition arranged and nonlin- ear golden section adaptive control. Through simulation platform we get and verify variable parameters fixed under the control strategy. At last we get availability of this scheme with the real platform experiment. The simulation results illustrate the effectiveness of the proposed method.
