Embodiment Construction
[0045] In order to describe the present invention more specifically, the GSC control method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0046] Such as figure 2 As shown, a GSC control method based on the resonant second-order sliding mode includes the following steps:
[0047] (1) Use the voltage Hall sensor 2 to collect the three-phase incoming line voltage U of the GSC a ~ U c and DC bus voltage U dc , using the current Hall sensor 3 to collect the three-phase incoming line current I of the GSC a ~ I c ;
[0048] Use the Clark transformation module 4 to pair the three-phase incoming line voltage U a ~ U c and three-phase incoming line current I a ~ I c Perform Clark transformation to obtain the α-axis component U of the three-phase incoming line voltage in the static α-β coordinate system α and the β-axis component U β And the α-axis component I of the three-phase ...
