Adaptive control

This paper presents a system that combines torque control algorithms based on a back-propagation neural network (BP-ANN) and an Adaptive Neuro-Fuzzy Inference System (ANFIS). The BP-ANN uses a multi-layer structure where the input layer processes factors such as load torque, rotational speed, and stator current, hidden layers model complex nonlinear interactions, and the output layer predicts optimal torque for AFPMSM operation.

The article focuses on developing an adaptive electronic stability controller for electric cars modelled on software MatlabSimulink. Design a vehicle stability controller within the scope of surveying the slippage of four tyres in the stability limit ellipse corresponding to the driving angle when using a fuzzy adaptive electronic stability controller (Fuzzy-ESC) compared to compared with the electronic stability control swarm optimization controller (PSO-ESP), it minimizes skids and vehicle rollovers during obstacle avoidance, lane changing, corner entry/exit and sudden acceleration.

In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.

The primary aim of this research was to further develop the sensing and estimation module of the CHMS framework with an improved multimodal inference model of MWL as needed for the application in aerospace CPHS. Here the focus of this research was on the implementation of a multimodal inference model of MWL that would be developed and experimentally tested. This was done with the purpose of studying the viability of real‐time system adaptation in aerospace systems.

The objectives of the study are: to extend the literature in several ways. First, the relationship between strategictype and organisational capabilities has been predominately investigated in the context of the private sector, not the public sector; To provide evidence about the comparative impacts of two contemporary control devices adapted by management of GBEs, as organisations that operated in a nexus between private sector market conditions and public sector ownership and oversight conditions; To provide evidence about the mix of congruency factors (i.e.

An efficient lighting system (Compact 3U) was successfully applied to the micropropagation of gloxinia and potato plants. To compare the in vitro growth of plantlets under Neon and Compact 3U lighting systems, gloxinia and potato shoots were cultured on suitable media at different light intensities: (1) 45 µmol m-2s -1 (under Neon lighting system as a control); (2) 45 µmol m-2s -1, (3) 60 µmol m-2s -1, and (4) 75 µmol m-2s -1 (under Compact 3U lighting systems).

Four pyruvate dehydrogenase kinase and two pyruvate dehydrogenase phosphatase isoforms function in adjusting the activation state of the pyruvate dehydrogenase complex (PDC) through determining the fraction of active (non-phosphorylated) pyruvate dehydrogenase component. Necessary adaptations of PDC activity with varying meta-bolic requirements in different tissues and cell types are met by the selective expression and pronounced variation in the inherent functional properties and effector sensitivities of these regulatory enzymes. ...

The classical metabolic control theory [Kacser, H. & Burns, J.A. (1973)Symp.Soc.Exp.Biol. 27, 65–104; Heinrich, R. & Rapoport, T. (1974)Eur. J. Biochem.42, 89–95.] does not take into account experimental evidence for correlations between enzyme concentrations in the cell. We investigated the implications of two causes of linear correlations: competition between enzymes, which is a mere physical adaptation of the cell to the limitation of resources and space, and regulatory correlations, which result from the existence of regulatory networks....
