The paper shows analogies between two separately evolved areas of PID control, the disturbance observer based controllers and the “intelligent” PID controllers. The simplest “intelligent” PID controller is represented by the “intelligent P” controller denoted as iP. It is designed for the simplified “ultra-local” integral plant models neglecting all internal plant feedbacks. These are included and...
The versatility of nanodevices dynamics may allow original architectures for computation but care should be taken to handle fluctuations arising at this scale. In the network of oscillatory units which we propose, bistability with down-quiescent and up-oscillatory states enable tolerance to noise in storage and retrieval dynamics for patterns or sequences. We illustrate this by simulations of the...
This paper highlights the main results of our research in the field of recurrence plot analysis in the last five years. It briefly discusses results in the study of the method itself, as well as in some applications of it, i.e. characterization of speech signals, detection and localization of partial discharges in electric cables, representation of transient signals, estimation of signal parameters,...
With the aim of manufacturing faster devices, the electronic industry scales down device's dimensions and is today entering into a nanoscale and Terahertz frequency regimes. In this work, we show how the reduction of the length L of the active region of two terminal devices implies (apart from the expected improvement of their dynamic behavior) a typically disregarded increment on the fluctuations...
Current nanometric IC processes need to assess the robustness of memories under any possible source of disturbance: process and mismatch variations, bulk noises, supply rings variations, temperature changes, aging and environmental aggressions such as RF or on-chip couplings. In the case of SRAM cells, the static immunity to such perturbations is well characterized by means of the Static Noise Margin...
There is a growing trend in the cognitive sciences to conceive of cognitive behavior as being distributed across brain, body and environment. However, the implications of such distribution for our understanding of biological robustness, which so far has been related to individual-based mechanisms alone, has rarely been discussed in the literature. We used the Evolutionary Robotics technique to examine...
A finite-time-convergent non-homogeneous robust exact differentiator is constructed, which provides for faster convergence compared with the standard homogeneous differentiator. The optimal asymptotic features of the standard differentiator are preserved. Computer simulation confirms the theoretical results.
In this study, the performance of eleven different filters are compared against a simulated maneuvering target. To provide applicability to a wide range of problems, a diverse set of metrics are considered. To ensure rigorous testing, a combination of randomly generated and fixed extreme trajectories are used. The effects of maneuvers are extracted by processing the results conditionally on maneuver...
Technology scaling in sub-100 nm regime has significantly shrunk the SRAM stability margins in data retention, read and write operations. Conventional static noise margins (SNMs) are unable to capture nonlinear cell dynamics and become inappropriate for state-of-the-art SRAMs with shrinking access time and/or advanced dynamic read-write-assist circuits. Using the insights gained from rigorous nonlinear...
