摘要：
The compensation of inverter nonlinearity is of great significance for improving the control performance of permanent magnet synchronous motor drive systems. In this article, an online inverter nonlinearity compensation method based on the adaptive gain second order generalized integral is proposed for obtaining dq-axis current harmonics caused by inverter nonlinearity. Therefore, the complex offline test of the inverter nonlinearity can be avoided. In addition, considering the phase shift of the second order generalized integral filter and the time delay caused by controllers, a suppression strategy based on self-adjustment a bandwidth method is proposed. Finally, the method is verified on an 11.7kW permanent magnet motor test platform.
