摘要
为了提高永磁同步电机的动态性能,提出一种基于永磁同步电机电流环有限时间的控制方法,即电机速度环采用传统PI调速控制、电流环基于有限时间控制的策略。MATLAB仿真结果表明:相较于传统的双PI控制电流环、速度环的策略,调整后基于有限时间的策略引入二阶扩张状态观测器,削弱不确定性扰动对系统的负面影响,使系统动态动态性能更佳,在快速跟踪转速指令、缩小转速超调量、缩短系统调整时间方面具有优势。
In order to improve the dynamic performance of permanent magnet synchronous motor(PMSM), a finite time control method based on current loop of PMSM was proposed. The method was as follows: traditional PI speed control strategy was adopted for the speed loop, and the finite time control strategy was adopted for the current loop. The MATLAB simulation results show that: compared with traditional double PI control strategy for current loop and speed loop, using the adjusted strategy based on finite time introducing the second-order extended state observer, the negative impact of uncertain disturbance on the system is weakened, the dynamic performance of the system is better. It has advantages in fast tracking speed command, reducing speed overshoot and shortening system adjustment time.
