- 摘要:
- 在永磁同步电机(PMSM)控制系统的速度环控制中运用自抗扰控制器(ADRC)，针对速度环特性设计一阶ADRC；对其中二阶扩张状态观测器（ESO）进行误差理论分析，用faln函数替换ESO中传统的fal函数以此提高观测精度，并通过Lyapunov对改进ESO进行收敛性判断；最后，将改进ESO的ADRC应用在永磁同步电机矢量控制系统转速控制中，仿真结果表明，改进ADRC比传统ADRC具有更好的抗扰效果。
- Abstract:
- In the vector system of permanent magnet synchronous motor outer ring control using self-annihilating controller, design the first-order ADRC for the characteristics of the outer ring; carry out the error theory analysis of the second-order ESO, then improve the ESO, replace the traditional fal function by the faln function to improve the observation accuracy of the dilated state observer, and Lyapunov to determine the convergence of the improved second-order ESO; finally, the second-order ESO will be improved. The simulation results show that the improved ADRC has better immunity effect than the traditional ADRC in the application of permanent magnet synchronous motor vector control system.
