This paper presents some further results on sliding mode control for a class of nonlinear systems with bounded uncertain parameters. A finite-time sliding manifold is proposed by incorporating piecewise defined function of time into the existing terminal sliding manifold, based on which a novel time-varying finite-time sliding mode controller is proposed. The proposed control strategy eliminates the...
This paper presents a general form for the fast terminal sliding mode (FTSM). It is shown that the proposed form not only includes the conventional FTSM, but also provides new types of FTSM which can have a faster convergence rate than the conventional one. More importantly, the convergence time of the new FTSM models is bounded for any initial value, which means an upper bound of the convergence...
Unequal error protection is the key to future transport of multimedia data. The paper presents an overview of some new approaches realizing UEP properties in physical transport, especially multicarrier modulation, or with LDPC and turbo codes. For multicarrier modulation, a UEP bit-loading method is described allowing for an arbitrary number of classes, arbitrary SNR margins between the classes and...
