Abstract

This paper examines some current controllings of velocity of electrical motor that are popular in technical books especially for Linear Functions with Parabolic Blends trajectory control (LFPB) and Minimum- Time trajectory control (MT). This paper also proves that the LFPB with shortest starting time is suitable with a concrete motor and dynamic system. This version of controlling seems prevail over the Minimum-Time Control that are mentioned in some professional technical books.
