LYAPUNOV-TYPE THEOREMS FOR ESTIMATION OF OUTPUT OF CONTROL SYSTEM WITH PERIODIC DIFFERENTIABLE NONLINEARITY
For multidimensional systems of indirect control with periodic differentiable nonlinearities
the problem of cycle-slipping is investigated. By means of generalized Lyapunov periodic functions
and Yakubovich-Kalman frequency theorem, new frequency-algebraic estimates for a number
of slipped cycles are obtained.
