The EPLL scheme is chacterized by an error filter and a phase-feedforward term that are embedded in the estimation algorithm for improved noise rejection and transient performances. By designing the error filter and by selecting the parameters of the PLL according to the guidelines suggested by the stability proof, the technique addressed in the paper allows to cope with the presence of measurement bias while damping the effect of high-frequency noise and harmonics. Simulation comparisons show the effectiveness of the proposed estimation technique. date: 2014-02-12 date_type: published publisher: IEEE official_url: https://doi.org/10.1109/CDC.2014.7040022 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1689371 doi: 10.1109/CDC.2014.7040022 isbn_13: 9781479977468 lyricists_name: Chen, Boli lyricists_id: BCHEB76 actors_name: Chen, Boli actors_id: BCHEB76 actors_role: owner full_text_status: public pres_type: paper series: IEEE Conference on Decision and Control publication: 2014 IEEE 53RD ANNUAL CONFERENCE ON DECISION AND CONTROL (CDC) volume: 2015-F number: February place_of_pub: Los Angeles, CA, USA pagerange: 4071-4076 pages: 6 event_title: 53rd IEEE Conference on Decision and Control event_location: Los Angeles, CA event_dates: 15 Dec 2014 - 17 Dec 2014 issn: 0191-2216 book_title: 53rd IEEE Conference on Decision and Control citation: Pin, Gilberto; Karimi-Ghartemani, Masoud; Chen, Boli; Parisini, Thomas; (2014) Sinusoidal Signal Estimation from a Noisy-Biased Measurement by an Enhanced PLL with Generalized Error Filtering.
