RISResonance Analysis of Fractional-Order Mathieu Oscillator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The resonant behavior of fractional-order Mathieu oscillator subjected to external harmonic excitation is investigated. Based on the harmonic balance (HB) method, the first-order approximate analytical solutions for primary ...
A Gait Trajectory Control Scheme Through Successive Approximation Based on Radial Basis Function Neural Networks for the Lower Limb Exoskeleton Robot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stability control is critical to the exoskeleton robot controller design. Considering the complex structural characteristics of lower limb exoskeleton robots, the major challenge of the controller design is the accuracy ...
Trajectory-Tracking-Based Adaptive Neural Network Sliding Mode Controller for Robot Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unpredictable disturbances and chattering are the major challenges of the robot manipulator control. In recent years, trajectory-tracking-based controllers have been recognized by many researchers as the most promising ...
A Novel Nonlinear Disturbance Observer Embedded Second-Order Finite Time Tracking-Based Controller for Robotic Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Robotic manipulators are complex and dynamic nonlinear mechanical systems subject to numerous uncertainties, such as payload variations, frictions, and unmodeled dynamics. To mitigate the uncertainty caused by these ...
