基于PCH控制的永磁同步电动机自适应L2扰动抑制

针对隐极永磁同步电动机（permanent magnet synchronous motors,PMSM）速度控制易受定子电阻、定子电感、负载转矩变化的影响，采用端口受控哈密顿（port—con—trolled hamiltonian，PCH）控制与自适应L2扰动抑制相结合的方法设计了PMSM的速度控制器。应用L2增益控制原理对负载扰动进行有效地抑制，在L2增益控制的基础上，引入自适应方法，减小PMSM定子电阻和电感变化的影响。文中建立了基于状态误差PCH控制的PMSM自适应L2扰动抑制仿真模型。仿真结果表明，用L2扰动抑制可以对负载扰动进行有效抑制，更好的减小误差，获得的效果更佳。

Adaptive L2 Disturbance Attenuation of PMSM Based on Hamiltonian Systems Control Theory

Aiming at that the control of the non-salient pole permanent magnet synchronous motor easily affected by changes of stator resistance,stator inductance and load torque,a novel PMSM speed controller is presented based on port-controlled Hamiltonian(PCH)systems theory and adaptive L2 gain control method.Firstly,we apply L2 disturbance attenuation to restrain the influence of load torque changes and then use adaptive control to reduce the influence of stator resistance and stator inductance changes.In this paper,the simulational model of adaptive L2 disturbance attenuation control is built based on the state error PCH control method.The simulation results show that the proposed scheme has a good performance and practical application prospects.
