چکیده

ontrol of underactuated biped robots is one of the challenging problems in the robotics field. The main difficulties of this problem that make it hard to control are its highly nonlinear dynamics, open-loop instability and impact event at the end of each step. Partial feedback linearization is a method to control underactuated systems but it is not robust against uncertainties and disturbances. This fact restricts the performance of the method to control walking or running of biped robots. In this paper we propose a fuzzy partial feedback linearization controller to improve this drawback mainly. Numerical simulations verify the effectiveness of the proposed method to generate stable bipedal walking gaits robustly against disturbances.

Robust Trajectory Free Model Predictive Control of Biped Robots with Adaptive Gait Length

This paper employs nonlinear disturbance observer (NDO) for robust trajectory-free Nonlinear Model Predictive Control (NMPC) of biped robots. The NDO is used to reject the additive disturbances caused by parameter uncertainties, unmodeled dynamics, joints friction, and external slow-varying forces acting on the biped robots. In contrary to the slow-varying disturbances, handling sudden pushing ...

Type-2 Fuzzy Logic Controller Using SRUKF-Based State Estimations for Biped Walking Robots

Walking motions of biped robots have features of humanoid and intelligent. Generally, when we human are walking, we may control the walking motions using qualitative instructions, such as linguistic “slow” or “fast,” “forward” or “backward,” “big step” or “small step”. This motivates us to design a fuzzy controller for biped robots. Furthermore, to improve the robustness of the biped walking sy...

Control of Underactuated Biped Robots Using Event Based Fuzzy Partial Feedback Linearization

Underactuated biped robots control is one of the interesting topics in robotics. The main difficulties are its highly nonlinear dynamics, open-loop instability, and discrete event at the end of the gait. One of the methods to control underactuated systems is the partial feedback linearization, but it is not robust against uncertainties and disturbances that restrict its performance to control b...

From Passive Dynamic Walking to Passive Turning of Biped walker

Dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. Formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. This study is aimed to elaborate this notion in the case of three dimensional (3D) walking and extend it f...
