Regional Boundary Gradient Closed Loop Control System and Γ*AGFO-Observer

Disturbance Observer Based Closed Loop Force Control for Haptic Feedback

Most commonly used impedance-type haptic interfaces employ open-loop force control under the assumption of pseudostatic interactions. Advanced force control in such interfaces can increase simulation fidelity through improvement of the transparency of the device, and can further improve robustness. However, closed loop force-feedback is limited both due to the bandwidth limitations of force sen...

Asymptotic Regional Boundary Observer in Distributed

The purpose of this paper is to study the concept of asymptotic regional observer in connection with the characterizations of sensors. We give various results related to different types of measurements, of domains and boundary conditions. Furthermore, we show that the measurements structures allow the existence of regional observer and we give a sufficient condition for such observer. We also s...

Closed Loop Control

Background The purpose of this study was to evaluate electrode temperatures obtained using a radiofrequency ablation system that incorporates closed loop feedback control to achieve preset target electrode temperatures and to determine if closed loop temperature control results in a lower incidence of developing a coagulum. Methods and Results Two hundred seventy patients underwent catheter abl...

Closed Loop Control Methods

In this paper, a systematic overview of PLL-based closed-loop control methods for interleaved DCM/CCM boundary boost PFC converters is presented. It is shown that the PLL-based closed-loop methods always provide stable operation, unlike the open-loop control methods, where the only method which results in stable operation is the slave synchronization to the turn-on instant of the master with cu...
