Abstract
Stability criterion for a linear time-varying (LTV) system with one harmonic time-varying coefficient in feedback is suggested. The found criterion is based on the hypothesis that the linear time-invariant (LTI) part of the system is a low-frequency filter. The criterion is simple and suitable for calculation of stability borders for LTV systems. The suggested criterion is compared with a numerical experiment, Bonjiorno criterion, stationarization method.
