摘要: Abstract In order to improve the plasma control performance and enhance capability for advanced control, new algorithms such as PEFIT/ISOFLUX shape feedback quasi-snowflake development vertical under power supply, have been implemented experimentally tested verified in EAST 2014 campaign. P-EFIT is a rewritten version of EFIT aiming at fast real-time equilibrium reconstruction by using GPU parallelized computation. Successful was established dedicated experiment. Snowfldivertor has advantage spreading heat over divertor target (QSF) configuration achieved discharges with Ip = 0.25 MA Bt = 1.8T, κ∼1.9, position control. The achieve QSF preliminary PEFIT initial experimental test done. For more robust instability inner coil (IC) its supply upgraded. A algorithm combination Bang-bang PID controllers developed. It shown that together results higher controllability.
