چکیده

An algorithm for generating quasi-harmonic self-oscillations with a uniformly widened spectral line is presented. The based on the equation of motion Thomson-type DT-oscillator, which introduced random effect in form band-pass white noise. Two types effects are implemented: additive and parametric. Spectral characteristics generated were analyzed by numerical experiment. shown to generate amplitude-frequency fluctuations. Frequency fluctuations set Lorentz (resonant) shape central part self-oscillation power spectrum, amplitude noise pedestal line. Based analysis statistical frequency DT-oscillator impact, parametric proposed. In it, resonance oscillating system Thomson subject perturbations. results experiments generators oscillations given.

FINITE-TIME PASSIVITY OF DISCRETE-TIME T-S FUZZY NEURAL NETWORKS WITH TIME-VARYING DELAYS

This paper focuses on the problem of finite-time boundedness and finite-time passivity of discrete-time T-S fuzzy neural networks with time-varying delays. A suitable Lyapunov--Krasovskii functional(LKF) is established to derive sufficient condition for finite-time passivity of discrete-time T-S fuzzy neural networks. The dynamical system is transformed into a T-S fuzzy model with uncertain par...

Line of Sight (LOS) rate estimation in strap down seekers using discrete-time extended state observer.

The line of sight (LOS) rate is a parameter that is needed to calculate the acceleration applied to missiles by the proportional guidance laws in order to hit the target. This rate is usually measured using gimbaled seekers. However, if the type of missile seeker be strap down, the LOS rate must be calculated from deriving the missile's seeker output angles or estimation methodes. The derivatio...

Admissibility analysis for discrete-time singular systems with time-varying delays by adopting the state-space Takagi-Sugeno fuzzy model

This paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space Takagi-Sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. Lyapunov Krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...

T-S FUZZY MODEL-BASED MEMORY CONTROL FOR DISCRETE-TIME SYSTEM WITH RANDOM INPUT DELAY

A memory control for T-S fuzzy discrete-time systems with sto- chastic input delay is proposed in this paper. Dierent from the common assumptions on the time delay in the existing literatures, it is assumed in this paper that the delays vary randomly and satisfy some probabilistic dis- tribution. A new state space model of the discrete-time T-S fuzzy system is derived by introducing some stocha...
