Input-to-state stability for discrete-time time-varying systems with applications to robust stabilization of systems in power form [PDF]

open access: yes, 2005
Input-to-state stability (ISS) of a parameterized family of discrete-time time-varying nonlinear systems is investigated. A converse Lyapunov theorem for such systems is developed.

Fixed‐time prescribed performance control method for nonlinear systems with unknown time‐varying parameters

open access: yesIET Control Theory & Applications
In this study, it is considered that the question of adaptive tracking control of nonlinear systems containing unknown time‐varying parameters. To optimize the control effect, a fixed‐time control strategy is adopted, in which the upper bound of the ...

On the price and income elasticity of consumption in EU economies

open access: yesEkonomický Časopis
Although the marketing literature is abundant with studies dealing with the responsiveness of consumption to price changes, not much has been said about the elasticity of household expenditures from a macroeconomic perspective.

Time-varying parameters as ridge regressions

open access: yesInternational Journal of Forecasting
Time-varying parameters (TVPs) models are frequently used in economics to capture structural change. I highlight a rather underutilized fact -- that these are actually ridge regressions. Instantly, this makes computations, tuning, and implementation much easier than in the state-space paradigm.

A New Varying-Parameter Design Formula for Solving Time-Varying Problems

open access: yesNeural Processing Letters, 2020
A novel finite-time convergent zeroing neural network (ZNN) based on varying gain parameter for solving time-varying (TV) problems is presented. The model is based on the improvement and generalization of the finite-time ZNN (FTZNN) dynamics by means of the varying-parameter ZNN (VPZNN) dynamics, and termed as VPFTZNN.

Expected optimal feedback with Time-Varying Parameters [PDF]

open access: yes
In this paper we derive, by using dynamic programming, the closed loop form of the Expected Optimal Feedback rule with time varying parameter. As such this paper extends the work of Kendrick (1981, 2002, Chapter 6) for the time varying parameter case ...
