摘要:

针对永磁同步电机存在的周期性脉动问题,提出了一种二阶PD型迭代学习控制策略(ILC),然后利用Lebesgue-p范数对系统误差进行分析,使它严格意义上满足单调收敛性。将一阶和二阶迭代学习控制的收敛速度进行了比较,得出二阶PD型迭代学习控制性能更优。同时提出二阶滑模观测器估算转子位置,通过配置比例、微分增益可获得快速收敛速度。最后,系统仿真及实验证明了系统的有效性。

Abstract:

In order to solve the problem of torque ripple of permanent magnet synchronous motor(PMSM), a second-order PD-type iterative learning control strategy was raised, Lebesgue-p norm was used to analyzed the system tracking error, so that it strictly satisfies the monotonic convergence. The convergence speed of the first-order and the second-order ILC rule was compared, turn out that the second-order PD-type iterative learning control was better. The two-order sliding mode observer was proposed for rotor position estimation, the observer could achieve fast convergence speed through proportion and integral gain. Lastly, simulation and experimental results show the effectiveness of the system.

Key words: permanent magnet synchronous motor (PMSM), iterative learning control (ILC), second-order sliding mode observer, Lebesgue-p norm
