The hydrostatic actuation system based on linear actuators improves the complex piston force and long transmission path of traditional electro-hydrostatic actuator (EHA). However, new nonlinear factors in direct-driven are introduced into system, which present challenges to modeling control. To improve accuracy performance prediction, this paper analyzed working characteristics an electromagnet...

Advancements have been made in the field of vehicle dynamics, improving handling and safety through control systems such as Antilock Braking System (ABS). An ABS enhances braking performance steerability a under severe conditions by preventing wheel lockup. However, its degrades on rough terrain resulting an increased lockup stopping distance compared to without. This is largely result noisy me...

In robotic manipulators, feedback control of nonlinear systems with fast finite-time convergence is desirable. However, because the parametric and model uncertainties, robust tuning manipulators pose many challenges related to trajectory tracking system. This research proposes a state-of-the-art algorithm, which combination integral terminal sliding mode (FIT-SMC), exact differentiator (RED) ob...

During the last two decades, exoskeleton robot-assisted neurorehabilitation has received a lot of attention. The major reason for active research in rehabilitation is its ability to provide various types physical therapy at different stages and neurological recovery. performance greatly influenced by robot motion control system. Robot dynamics are nonlinear, but many linear schemes can adequate...

The main goal of this work is to develop a comprehensive methodology for predicting wear in planar mechanical systems with multiple clearance joints and investigating the interaction between joint clearance, driving condition, wear. In process, an effective contact surface discretization method together Lagrangian are used establish dynamic equation multibody system. Considering change surface,...

This paper presents an improved observer-based robust adaptive control strategy for a class of nonlinear systems that have two features; i. the coupling of unmeasured states and unknown parameters exist at the measured states dynamics, ii. unknown deadzone exists at the system actuation. At first, the bounds of the dead zone parameters are assumed to be known and a suitable control strategy is ...

Within the European project e-SAFE (Energy and Seismic AFfordable rEnovation solutions), this paper presents experimental tests modeling attempts for a class of Asymmetric Friction Connections (AFCs) tested in laboratories Norwegian University Life Sciences. The AFCs are part seismic retrofitting solution, called e-CLT, based on installing Cross-Laminated Timber (CLT) panels reinforced concrete...
