基于标幺化两相吸引律的永磁同步电机有限时间速度控制
A finite-time control method for permanent magnet synchronous motors based on a per-unit two-phase attraction law
摘要
Abstract
A finite-time speed control method based on per-unit two-phase attraction law is proposed for permanent mag-net synchronous motors(PMSM)suffering from load torque and other disturbances,etc.Firstly,the speed is trans-formed into the per-unit value to construct a per-unit two-phase attraction law with ideal error dynamic characteristic curve.Then,based on the two-phase attractive law,a speed controller is designed.At the same time,a finite time extend state observer is designed to estimate the unmodeled dynamics and external disturbances in the system,and finite time convergence of the speed tracking errors is realized.Secondly,Lyapunov function is constructed to ana-lyze the stability of the proposed control method.Finally,the proposed method is verified in a PMSM drive plat-form.The experimental results show that the proposed method achieves fast speed tracking without overshoot,and demonstrate its good dynamic and steady-state performance and anti-disturbance ability.关键词
