| 英文摘要 |
| Aiming at the periodic ripples of permanent magnet synchronous motor speed caused by non-ideal factors,
such as current measurement error and dead-zone effect of inverter, this paper designs a plug-in adaptive repetitive controller
in the speed loop to achieve smooth and stable control of the motor speed. Firstly, the mechanism of the periodic steady-state
speed ripples due to non-ideal factors is analyzed for permanent magnet synchronous motor. Secondly, a zero-phase FIR
low-pass filter, a linear phase compensator and the repetitive controller gain are designed to ensure the stability of the system
with the adaptive repetitive controller. On this basis, the fal function is introduced to solve the overshoot problem of the
dynamic regulation process of the system caused by the added repetitive controller. Experimental results can demonstrate
the effectiveness of the proposed method. |
