The closed-loop transfer function of a plant controlled with a classical feedback controller, depends on the dynamics of the plant. Since most feedforward tracking controllers are designed based on this closed-loop transfer function, they are not robust against plant model uncertainties. Sliding-mode controllers have the property that when the system is on the switching line, the closed-loop be...

In this paper we consider a large class of partial diierential equations (PDEs) with distributed control and with a time-delay in the feedback loop. We analyze the relationship between the poles of the closed-loop transfer function and the exponential modes of the underlying retarded PDE in order to derive internal stability properties from external ones. Our approach is based on a combination ...

The industrial sector is nowadays experiencing a digital transformation motivated by the Industry 4.0 paradigm. Concepts such as data-driven models, Artificial Neural Networks (ANNs), and Transfer Learning (TL) are part of current vocabulary in management control topics. For that reason, this paper application TL techniques proposed to derive new ANN-based structures from pre-existing ones. Not...

introduction this study was conducted to evaluate the involvement of body organs such as the lungs in systemic lupus erythematosus (sle). little information exists on lung involvement in lupus patients without respiratory symptoms; we aimed to evaluate the characteristics of lung gas transfer in female sle patients using carbon monoxide diffusion capacity (dlco) in comparison with a control gro...

This paper studies robustness of MIMO control systems with parametric uncertainties, and establishes a lower dimensional robust stability criterion. For control systems with interval transfer matrices, we identify the minimal testing set whose stability can guarantee the stability of the entire uncertain set. Our results improve the results in the literature, and provide a constructive solution...

Abstract—In this document, we introduce CapStart TCP, an adaptive Slow Start scheme that consistently achieves fast TCP file transfer times regardless of high speed network scenario. Once the TCP session is established, we estimate TCP session path capacity scenario, and tune the transport protocol to deliver fast transfer times. We show that our capacity estimator works well even when the sess...

The wheel speed control problem of an automotive powertrain equipped with a conventional spark-ignition engine directly connected to a continuously variable transmission (CVT) and an electronic throttle is considered. We revisit the seminal work by Guzzella and Schmid and show that the control structure that dedicates the throttle actuator to maintaining engine operation at the maximum fuel eff...
