Tracking mode implementation features for the synchrophase electric drive

Abstract

The actual synchrophase electric drive (SPED) control methods are built with a number of assumptions. Therefore the methods are full of flaws. The known time quasioptimal control method is based on the acceleration constancy assumption. It makes the phasing process inaccurate. Additional phasing process is needed. Phase plane method, control theory, electrical machines theory is used in the work. The new phasing method for the SPED is proposed. The method is based on the accurate measurement of the angular velocity mismatch. It allows to improve the control process quality characteristics.
