The research on self-excited induction generators (SEIGs) feeding IMs can be divided into two main areas: without and with regulating power electronics devices.
Also, the use of the two-tailed current sources and the self-excited tube structure and their impact on the increase of the oscillation frequency and the voltage swing at the output are examined.
This invariance of squeal propensity versus rotational velocity is likely in connection with the initial hypothesis of Coulombian friction; in fact, considering the friction coefficient constant with angular speed, also the friction force will be constant, which represents energy source of self-excited vibrations that cause the squeal, so a nonconstant friction coefficient should be considered.
In order to calculate the electromechanical mode associated with system oscillation, the self-excited method [17] is utilized by deriving the eigenvalue of (6) through the Newton iteration method.

Singaravelu and Velusami presented the capacitive VAR requirements to do the desired voltage regulation under changeable speed and load situations of the self-excited one-phased IG and three-phased SEIG with changeable number of poles [11].
The nonlinear aeroelastic system of an airfoil is a typical self-excited system, which can exhibit lots of nonlinear dynamical behaviors such as bifurcations, limit cycle oscillations (LCO), and chaotic responses [1, 2].
An all-digital MEMS tuning fork self-excited vibration control by phase-relation using time-A/D converter- (TAD-) based all-digital PLL (ADPLL), which uses no conventional analog method such as automatic gain control (AGC) or automatic level control (ALC), has been presented [10].
