In this paper, an adaption mechanism for control signal weighting factor in Generalized Predictive Control (GPC) Technique has been build. This factor changes according to the amplitude of the measured disturbance affecting the acid influent in pHNeutralization process. The main purpose of this adaption is to reduce rigorousness and severity of the manipulated variable of alkaline flow actuator, which result in protecting the actuator from damage, so lengthen its life and shrinking the maintenance costs. The efficiency of the Adaption was observed by calculating the integral of the absolute value of the error (IAE) and the integral of absolute derivative signal (IADS) from simulation results.

This paper presents the possibility of replacing the mathematical
optimizer in the Model Predictive Control Algorithm (MPC) with a
Feedforward Neural Network Optimizer (FNNO). The optimizer
trained offline to reduce the cost function. This maintai
n the system
model of the system, which is essential in MPC to get accepted
accuracy. we solve optimization problem faster than the algorithms
of traditional optimization, which we built, based on digital
computing.
The chromatic dispersion of fiber is a major factor
causing distortion of the light signals, and if not being
addressed using accurate compensators it will lead to a
significant deterioration in the performance of optical system.
The value of chr
omatic dispersion is not fixed along the fiber,
and this necessitates the use of tunable dispersion
compensators which need information about the value of
dispersion which is done by dispersion monitoring.
This research is Interested in analyzing chromatic
dispersion technique based on the measuring of clock tone
power of transmitted data and which is commensurate with
the dispersion of the fiber. We found the relationship between
signal frequency with range and accuracy of measurement.
Also, the advantage of this technique to provide feedback
signal to tunable dispersion compensator. The results show
the extent of the improvement made in network performance.
VPItransmissionmaker program was used to simulate
the technique proposed.
We propose to control paraphrase generation through carefully chosen target syntactic structures to generate more proper and higher quality paraphrases. Our model, AESOP, leverages a pretrained language model and adds deliberately chosen syntactical
control via a retrieval-based selection module to generate fluent paraphrases. Experiments show that AESOP achieves state-of-the-art performances on semantic preservation and syntactic conformation on two benchmark datasets with ground-truth syntactic control from human-annotated exemplars. Moreover, with the retrieval-based target syntax selection module, AESOP generates paraphrases with even better qualities than the current best model using human-annotated target syntactic parses according to human evaluation. We further demonstrate the effectiveness of AESOP to improve classification models' robustness to syntactic perturbation by data augmentation on two GLUE tasks.
We describe a Plug-and-Play controllable language generation framework, Plug-and-Blend, that allows a human user to input multiple control codes (topics). In the context of automated story generation, this allows a human user lose or fine grained con
trol of the topics that will appear in the generated story, and can even allow for overlapping, blended topics. We show that our framework, working with different generation models, controls the generation towards given continuous-weighted control codes while keeping the generated sentences fluent, demonstrating strong blending capability.
