This paper deals with the control and the estimation of the visual feedback systems with a fixed camera. Firstly the fundamental representation and the nonlinear observer for the visual feedback system with four coordinate frames is established. Secondly the visual feedback system is composed by the control error system and the estimation error system. Next, we derive the passivity of the visua...

In this paper a hybrid passivity based and fuzzy type-2 controller for chaotic and hyper-chaotic systems is presented. The proposed control strategy is an appropriate choice to be implemented for the stabilization of chaotic and hyper-chaotic systems due to the energy considerations of the passivity based controller and the flexibility and capability of the fuzzy type-2 controller to deal with ...

The problem of passivity analysis finds important applications in many signal processing systems such as digital quantizers, decision feedback equalizers and digital and analog filters. This paper considers the passivity analysis problem for a large class of systems which involve uncertain parameters, time delays, quantization errors, and unmodeled high order dynamics. By characterizing these a...

We consider the passivity analysis and passivation problems for event-triggered feedback interconnected systems. Based on the location of the event-triggered samplers, we consider two event-triggered control schemes respectively: event-triggered sampler of plant output and event-triggered sampler of controller output. For both schemes, we first derive the conditions to characterize the level of...

This paper investigates a passivity-based control (PBC) for DC Motor drive system with PWM. In the paper, the port-controlled Hamiltonian system with dissipation (PCHD) model of the system is built and the interconnection and damping assignment passivity-based control (IDA-PBC) method is used for the design of the controller. The system simulation model is built based on MATLAB/Simulink and the...
