Increasing the rate-hardness of haptic interaction: Successive force augmentation approach (2017)
Presentation / Conference Contribution

There have been numerous approaches that have been proposed to enlarge the impedance range, however it is still a challenging issue to increase the rate-hardness of haptic interaction while maintaining stability. The actual perceived rate-hardness ha... Read More about Increasing the rate-hardness of haptic interaction: Successive force augmentation approach.

Multi degree-of-freedom successive stiffness increment approach for high stiffness haptic interaction (2016)
Presentation / Conference Contribution

In haptic interaction, stability and the object’s hardness perception are of great significance. Although numerous studies have been done for stable haptic interaction, however, most of them sacrifice the actual displayed stiffness as a cost of stabi...

Stable and transparent teleoperation over communication time-delay: Observer-based input-to-state stable approach (2016)
Presentation / Conference Contribution

In this paper, an observer-based input-to-state stable approach is proposed to stabilize teleoperation systems over communication time-delay with better transparency compared with passivity approaches. In this paper, input-to-state stable approach is... Read More about Stable and transparent teleoperation over communication time-delay: Observer-based input-to-state stable approach.

Increasing the impedance range of admittance-type haptic interfaces by using Time Domain Passivity Approach (2015)
Presentation / Conference Contribution

© 2015 IEEE. This paper proposes a method to increase the impedance range of admittance-type haptic interfaces. Admittance-type haptic interfaces are used in various applications that typically require interaction with high impedance virtual environm...

Stable bilateral teleoperation with input-to-state stable approach (2015)
Presentation / Conference Contribution

Passivity has been the most often used constraint for the controller design of bilateral teleoperation systems. However passivity has been suffering from its own design conservatism since this is a sufficient condition for stability and representing...

Network formulation and stability improvement of a bilateral teleoperation system with admittance-type master interfaces (2015)
Presentation / Conference Contribution

© 2015 IEEE. This paper introduces a network formulation of bilateral teleoperation systems with admittance-type master interfaces to improve their stability range with Time Domain Passivity Approach (TDPA). Since traditional network representation o... Read More about Network formulation and stability improvement of a bilateral teleoperation system with admittance-type master interfaces.

Stable admittance type haptic interaction based on time domain passivity approach (2015)
Journal Article

In this paper, we propose a stable and high transparent admittance haptic display even in free space haptic rendering. Because considering admittance haptic rendering as a one-port network is not enough to detect the active energy, new representation...

Input-to-state stable approach to release the conservatism of passivity-based stable haptic interaction (2015)
Presentation / Conference Contribution

© 2015 IEEE. Passivity has been a major criterion on designing a stable haptic interface due to many advantages. However, passivity has been suffering from its intrinsic conservatism since it only represents a small set of the whole stable region. Th...

6-DOF extension of memory-based passivation approach for stable haptic interaction (2014)
Journal Article

© 2014, Springer-Verlag Berlin Heidelberg. This paper extends previously proposed memory-based passivity approach (MBPA) to 6 degrees-of-freedom (DOF) haptic interactions. By introducing 6-DOF virtual proxy and virtual object, connected with haptic i... Read More about 6-DOF extension of memory-based passivation approach for stable haptic interaction.
