Journal ArticleDOI
A Disturbance Observer Based Sliding Mode Control for a Class of Underactuated Robotic System With Mismatched Uncertainties
TL;DR: The stabilities of both the disturbance observer and the controlled closed-loop system are proved by the Lyapunov theorem and a choice method of optimal gain matrices of the high-order disturbance observer is obtained as the solution of an optimization problem.
Journal ArticleDOI
Fuzzy support vector machine for classification of EEG signals using wavelet-based features.
TL;DR: The proposed FSVM model has potential in reducing the effects of noise or outliers in the online classification of EEG signals in BCIs and outperforms the SVM method.
Journal ArticleDOI
A real-time EMG pattern recognition method for virtual myoelectric hand control
TL;DR: A real-time electro-myogram (EMG) pattern recognition approach for the control of multifunction myoelectric hands using the support vector machine (SVM) and a novel feature selection method based on a depth recursive search algorithm.
Proceedings ArticleDOI
Incremental probabilistic latent semantic analysis for automatic question recommendation
Hu Wu,Yongji Wang,Xiang Cheng +2 more
TL;DR: An incremental recommendation algorithm based on Probabilistic Latent Semantic Analysis (PLSA) that can consider not only the users' long-term and short-term interests, but also users' negative and positive feedback is proposed.
Journal ArticleDOI
Review of rational total nonlinear dynamic system modelling, identification, and control
TL;DR: This paper brings several representative algorithms together, developed by the authors and their colleagues, to form an easily referenced archive for promotion of the awareness, tutorial, applications, and even further research expansion.
