Stability analysis of a two-mass TPN-BP electric drive circuit with non-linear load

Abstract

Gain factor of a proportional speed regulator is chosen via analysis of stability region. In an initially unstable double-ma AC electric drive, the selected gain provides required quality of transients in a wide spread of the following parameters: slope of rhe dropping section of speed-toraque characteristio, stiffness of the elastic link, and moment of inertia of the other mass
