— In this paper, a novel design of an Extremum-Seeking Controller (ESC) based on Sliding Mode Control (SMC) for a class of Single-Input-Single-Output (SISO) uncertain or unknown nonlinear systems is proposed. The corrective term of the proposed observer is used to estimate the uncertain system. Global exact tracking using only output-feedback is proven with(More)
Recent research has shown the speed advantage of extreme learning machine (ELM) and the accuracy advantage of sparse representation classification (SRC) in the area of image classification. Those two methods, however, have their respective drawbacks, e.g., in general, ELM is known to be less robust to noise while SRC is known to be time-consuming.(More)
— In this paper, the problem of designing a sliding mode controller for a class of uncertain fractional-order non-linear systems with 0 < q < 1 is addressed by using linear matrix inequality (LMI) method. A key analysis technique is enabled by proposed a fundamental boundedness lemma, which is used for rigorous stability analysis of fractional-order(More)

The present study mainly examines the cleft acquisition of Mandarin children. In our study, we observed learners' performances from four main perspectives, i.e., syntactic complexity effects, cleft types, age effects and developmental effects. The results of this study gave support that syntactic construction was an important factor affecting children's(More)
