In this paper, considering the contact transmission between heavy smokers and potential smokers, we propose a novel fractional smoking model. Moreover, introduce two intervention measures, i.e., media campaign adjuvant drug treatment, to model in order control spread of smoking. For controlled model, some important properties are discussed. Then, an optimal problem involving system. The existen...

In this paper, optimal design of hybrid low damping base isolation and magnetorheological (MR) damper has been studied. Optimal hybrid base isolation system has been designed to minimize the maximum base drift of low damping base isolation system where for solving the optimization problem, genetic algorithm (GA) has been used. In design procedure the maximum acceleration of the structure has ...

guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

This paper focuses on a strong approximability property for nonlinear affine control systems.We consider control processes governed by ordinary differential equations (ODEs) and study an initial systemand the associated generalized system.Our theoretical approach makes it possible to prove a strong approximability result for the above dynamical systems. The latter can be effectively applied to ...

The paper presents the way to use Lyapunov techniques to analyse and to assure stability of control systems with fuzzy PI controllers. The stability is assured based on a compensation of the input-output characteristic of the fuzzy blocks used in PI fuzzy controller. The compensation is made on fuzzy control law by the action in parallel of a crisp block for non-linear parts of input saturation...

In the presence of unknown time-varying disturbances and input saturation, this paper develops a robust nonlinear control law for the dynamic positioning (DP) system of ships using a disturbance observer, an auxiliary dynamic system, and the dynamic surface control (DSC) technique. The disturbance observer is constructed to provide the estimates of unknown time-varying disturbances, the auxilia...
