The paper presents passivity conditions for a class of stochastic Hopfield neural networks with state-dependent noise and with Markovian jumps. Our contributions are mainly based on the stability analysis of the class of stochastic neural networks considered, using infinitesimal generators of appropriate stochastic Lyapunov-type functions. The passivity conditions derived are expressed in terms...

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...

In this letter, we consider nonlinear network systems under unknown disturbances and address the problem of mixed input/output consensus , i.e., consensus among disjoint sets input output nodes. We develop two control schemes based on different notions passivity: 1) Krasovskii passivity 2) shif...

The desire for energy independence presupposes the use of various types elements generation from renewable sources, stand-alone operation which storage devices are required. A power complex created in this way must perform a number tasks that formed by management system. control system performs these and ensures proper static dynamic characteristics with many inputs outputs. results recent worl...

In this report, we study the distributed control problem of networked Euler-Lagrange(EL) systems with nonholonomic constraints. The reason for singling out this particular topic is that distributed control of networked Euler-Lagrange systems with nonholonomic constraints captures a large class of contemporary engineering problems, such as rendezvous problem and formation problem. We propose a n...

This paper presents a stability analysis of force-position teleoperation under general end-effector contact. The analysis is based on the finite and infinite zero structure of the multivariable root-locus resulting from modulation of the environment stiffness. The starting point is an analysis of the stability of robot force control, motivated by the observation that the human-operator in a for...

This paper discusses the (inverse) optimality and practical usage of passivitybased controls for distributed port-Hamiltonian systems. We first clarify that passivity-based controls, damping assignment and potential shaping can be derived from a linear quadratic type optimal control problem. Next, we describe the limitation of passivity-based boundary controls and propose a practical usage of t...

In recent works, IDA-PBC has been succesfully applied to mechanical control problems with no physical damping present. In some cases, the friction terms can be obviated without compromising stability in closed loop. However in methods that modify the kinetic energy, a controller designed for stabilizing the undamped system might loose passivity, a key property for stabilization, when damping is...

Current haptic (force feedback) telepresence systems operated over a communication network as, e.g. the Internet, require high packet rates for the transmission of the command and sensor signals. We propose a novel approach to reduce the network traffic by means of deadband control. Data packets are only sent if the sampled signal changes more than a given threshold value. Passivity based estim...
