In this paper we consider a parameter estimation problem for delay differential equations that are typical in the bioscience. The problem is motivated by a model of the dynamics of the intracellular development cycle of Chlamydia Trachomatis and can be formulated as a inverse problem for a system of delay equations. We derive the continuous sensitivity equations and show that the corresponding ...

This paper designs a robust close-formation control system with dynamic estimation and compensation to advance unmanned aerial vehicle (UAV) flights an engineer-implementation level. To characterize the wake vortex effect analyze sweet spot, continuous horseshoe method high accuracy is employed model vortex. The will be implemented in trailing UAV steer it spot hold its position. Considering ch...

Abstract The paper deals with the creation and implementation of a methodology for optimizing parameters cascade control machine tool axis drives. first part presents identification dynamic model based on experimental data from measuring dynamics. second describes controller model, selection optimization objective functions, constraint conditions. controllers is tuned by simulation using identi...

A dual-loop cycle for a domestic refrigerator-freezer (RF) has a large energy saving potential because of lower compression ratio due to higher evaporating temperature in the fresh food compartment (R)-operation, and the individual optimization flexibility for each loop, compared to a conventional refrigeration cycle. In this study, the optimization of the dual-loop cycle was carried out. The o...

The γ-optimization parameter is one of the key parameters for designing loop filters of phase-locked loop and optimal choice of γ depends on phase margin of the system. Here, we propose to study the impact of γ-optimization parameter and phase margin on closed loop gain of phase-locked loop for frequency synthesizer. A model has been developed and simulated, considering two different filter sec...

In many real-world domains, the presence of machines is becoming more ubiquitous to the point that they are usually more than simple automation tools for one-way interaction. As part of the environment amongst human users, it is necessary for these computers and robots to be able to interact back reasonably by either working independently around them or participating in a task, especially one w...

The main goal of our paper is to study the regularization problems which occur in predictive control of systems with severely ill-posed inverse model. We propose a new formulation of predictive control where the future controls are obtained as a solution of certain ill-posed inverse problem. This formulation leads to a possibility of closed loop on-line control of complex systems with ill-posed...
