| Abstract |
In this paper an inverter is taken to be a member of Variable Structure System (VSS). Park vector based variable structure control (VSC) methods are studied. A modified definition of the Park vector is introduced to handle the effect of zero phase-sequence component caused by an asymmetrical load. This paper focuses on the switching rule. A complex sliding surface is defined. The inverter is switched in such a way that the system trajectory gets as close to the sliding surface as possible. Experimental results are presented. |
