摘要

Design and analysis of a novel three phase discrete observer is proposed in this paper. A rotation matrix based on recurrence formula along with observer feedback matrix set for a particular frequency is used to formulate a structure such that accurate estimation is obtained for the designed frequency. This observer is used to filter out the switching noise percolating into the control loop by providing ripple free feedback variables in d-q control. Also this helps in achieving faster transient response in current control. Simulation of decoupled current control of a stand-alone three phase Inverter is done to evaluate the performance and feasibility of the proposed observer.
