The purpose of this paper is to present a new modified parametric algebraic model for MR damper in controlling the semi-active suspension system. Except for its accuracy, modified algebraic model is additionally more preferable in terms of its low computational expenses compared to differential modified Bouc-Wen’s model that is extremely computationally demanding. The control part consists of t...

In this paper, we propose a new passivity-based synchronization method for two different chaotic systems. Based on Lyapunov stability theory and linear matrix inequality (LMI) approach, the passivity-based controller is presented to make the synchronization error system between two different chaotic systems not only passive but also asymptotically stable. It is shown that the proposed controlle...

Applying an evolutionary algorithm, we first develop the morphology of a simulated passive dynamic bipedal walking device, able to walk down a shallow slope. Using the resulting morphology and adding minimal motor and sensory equipment, a neural controller is evolved, enabling the walking device to walk on a flat surface with minimal energy consumption. The applied evolutionary algorithm fixes ...

Abstract This paper addresses the adaptive passivation of multi-input multi-output (MIMO) non-linear systems,with unknown parameters. The class of MIMO non-linear systems considered here has an explicit linear parametric uncertainty and it is made equivalent to a passive system by means of an adaptive controller with adaptive laws specially designed, which include suitable time-varying gains. T...

As smart homes become more widespread, the need for more natural forms of interaction in the home also increases. On the one hand, forcing a user to go to a central home controller at every required change does not make sense. On the other hand, having a different controller for each device is also quite overwhelming. Object-Specific Interfaces (OSIs) allow an interface customized to an object ...

This paper presents the integration of renewable energy sources such as photovoltaics, wind, and batteries to grid. The hybrid shunt active power filter (HSHAPF) is optimized with Gray wolf optimization (GWO) fractional order proportional integral controller (FOPI) for harmonic reduction under nonlinear unbalanced load conditions. With use GWO, parameters FOPI are tuned, which effectively minim...

This paper studies the non-fragile mixed H∞ and passive synchronization problem for Markov jump neural networks. The randomly occurring controller gain fluctuation phenomenon is investigated for non-fragile strategy. Moreover, the mixed time-varying delays composed of discrete and distributed delays are considered. By employing stochastic stability theory, synchronization criteria are developed...

Boost converters have nonminimum phase (NMP) characteristics, which makes the stable closed-loop control design difficult. Based on passive theory, this article proposes to add a feedforward loop in conventional double-loop closed compensate for NMP effect. Therefore, potential instability caused by can be avoided. Such compensation is especially useful dc microgrid applications where boost are...

| This is Part 1 of a two part paper on the design of intelligent controllers for a class of exercise machines. The control objective is to cause the user to exercise in a manner which optimizes a criterion related to the user's mechanical power. The optimal exercise strategy is determined by a biomechanical behavior of the individual user, which is assumed to satisfy an aane force-velocity rel...
