This paper concerns reduced-order stable controllers in a unified way for two typical examples of underactuated robots called the Acrobot and the Pendubot which are two-link planar robots moving in a vertical plane with a single actuator at joints 1 and 2, respectively. The main contributions of this paper are threefold. First, using properties of the mechanical parameters of two-link planar robots,...
In order to cultivate talents and raise the design ability for power converters at engineering education on campus, the design methodology of a flyback dc/dc converter is introduced step by step in this paper. First of all, the fundamental of switching power converters is analyzed and described in this paper. Later, the power converter is modeled and simulated. The open and closed loop controls of...
In order to explore why some learners have better learning effects with the simulation tool, and the others do not, the researchers used the quasi-experimental design and think-aloud method to investigate the relations between individual differences and learning effects from studentspsila learning processes with the simulation tool, dynamic simulation assisted statistical learning (DSASL). The results...
This paper proposes a new face recognition approach by using Independent Component Analysis (ICA) and Ensemble Classifiers based on Support Vector Machine (SVM). Firstly, to improve the quality of the face images, a series of image pre-processing techniques are used. Then the ICA based on Kernel Principal Component Analysis (KPCA) and FastICA is employed to extract features. At last, appropriate classifiers...
