Linear control

This paper presents a voltage and frequency adjustment method based on fuzzy logic to minimize voltage and frequency deviation to improve power quality in microgrids. This controller includes a Droop controller combined with fuzzy logic, the fuzzy logic block will control to change in the slope of the Droop characteristic curve when the load changes.

This study focuses on electrospinning with linear spinnerets to overcome the drawbacks of existing electrospinning methods. The aim of this study is thus to design and realise the linear spinnerets that hold the advantages in generating multiple polymer jet with a low applied voltage and easy controlling.

This study develops an online unmanned UAV path-planning strategy for autonomous search and localisation of RF emitter. The UAV is equipped with Receiver Signal Strength (RSS) sensors to localise stationary radio frequency (RF) emitter. A high-fidelity non-linear measurement model of RF propagation in an urban environment is adopted for this purpose. The measurement model of the likelihood function is considered a Gaussian mixture.

We study axial core oscillations due to xenon poisoning in thermal neutron nuclear reactors with simple 1D models: a linear one-group model, a linear two-group model, and a non-linear model taking the Doppler effect into account.

The transcription patterns of 64 linear double stranded DNA templates obtained with T7 RNA polymerase were investigated. These templates consisted of 17 nucleotide-long sequences under the control of the minimal bac-teriophage T7 promoter and represented all possible combinations of nucleotides at positions +8, +10 and +11.

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....

Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

LINEAR SIGNAL CONDITIONING TO SIX-SIGMA CONFIDENCE INTRODUCTION Economic considerations are imposing increased accountability on the design of analog I/O systems to provide performance at the required accuracy for computerintegrated measurement and control instrumentation without the costs of overdesign. Within that context, this chapter provides the development of signal acquisition and conditioning circuits, and derives a unified method for representing and upgrading the quality of instrumentation signals between sensors and data-conversion systems....
