Gait pattern generation under disturbance force

2016 16th International Conference on Control, Automation and Systems (ICCAS), 2016
This paper describes a gait pattern generation and the mechanisms of a biped humanoid robot that has 42 DOFs in total. The movable angles of the joints of the biped robot are about the same as those of a human. Its height is 1.66 [m] and its weight is 62.5 [kg].

Spatial Autoregressive Models with Generalized Spatial Disturbances

Statistica Sinica
Summary: We propose a spatial autoregressive model with generalized disturbances to simultaneously model the spatial effects between the response variables and those between the disturbance terms. By directly modeling the covariance matrix of the disturbance terms as a polynomial function of a row-normalized adjacency matrix with a prespecified upper ...

Disturbance attenuation for general nonlinear systems

Proceedings of 1994 33rd IEEE Conference on Decision and Control, 2002
This paper presents some solutions to the problem of disturbance attenuation via state feedback and measurement feedback for general nonlinear systems, respectively. The results given in this paper generalize those for affine nonlinear systems. >

Real generation of power quality disturbances

2015 Third International Conference on Technological Advances in Electrical, Electronics and Computer Engineering (TAEECE), 2015
Nowadays, feature of electrical power becomes a main subject that takes concern of utilities and its customers. Due to undesired disturbances in power quality (PQ) field, many studies took place to analyze and detect the causes of power quality disturbances (PQD). This paper presents a testing of generated PQD on BIOPAC electrocardiogram (ECG).

Generating Chaos by Parameter Periodic Disturbance

2006 6th World Congress on Intelligent Control and Automation, 2006
A parameter periodic disturbance method is proposed to construct chaos. By numerical analysis and circuit experiment, a second-order non-chaotic system is illustrative to validate that the proposed approach can actually generate chaos.

Finite-Time Sliding Mode Control for NPC Converters With Enhanced Disturbance Compensation

IEEE Transactions on Circuits and Systems Part 1: Regular Papers
In this paper, a generalized proportional integral observer (GPIO)-based finite-time sliding mode control scheme is proposed to enhance the convergence rate and disturbance rejection capacity of the grid-connected three-level neutral-point-clamped (NPC ...

Disturbance Force Generator for Biped Robots

2016
This paper describes the mechanism and control of a disturbance force generator that is able to evaluate disturbance compensation control of biped robots quantitatively. The disturbance generator consists of a base, a motor drive system and a suspension system. In order to apply a disturbance force to a biped humanoid robot, a wire wound on a pulley of
