This paper presents a robustness-improving discrete-time current controller utilizing predictive current control (PCC) for permanent magnet linear synchronous motor (PMLSM). The stability and robustness of the PCC system is highly affected by the parameters mismatch between the controller and the plant, and the inherent digital control delay can limit the bandwidth. Toward this, an integrated method...
The widespread availability of audio editing software has made it very easy to create forgeries without perceptual trace. Copy-move is one of popular audio forgeries. It is very important to identify audio recording with duplicated segments. However, copy-move detection in digital audio with sample by sample comparison is invalid due to post-processing after forgeries. In this paper we present a method...
This paper focuses on the robust stabilization for uncertain fuzzy singular systems with interval time-varying delay. First, the uncertainties are converted to disturbance input, the conditions to enable the closed-loop system to be stable are established and a state feedback controller which guarantees that the closed-loop system will be regular, impulse free and robust stable is presented in terms...
This paper present a discriminative sparse point matching method (DSPM) for tracking generic objects in vision applications. Different from the conventional tracking methods that involves the construction of high-level or self-learning features, DSPM particularly focuses on a optical flow based point matching optimization method for overcoming the variation of object deformation in motion. The algorithm...
The development of a geometric invariant audio watermarking scheme without degrading acoustical quality is challenging work. This paper proposes a multi-bit spread-spectrum audio watermarking scheme based on a geometric invariant log coordinate mapping (LCM) feature. The LCM feature is very robust to audio geometric distortions. The watermark is embedded in the LCM feature, but it is actually embedded...
