This paper proposes an adaptive global asymptotic stable (adaptive GAS) control scheme for the compensation of friction and disturbance effect to control robot manipulators. This control method integrates both model reference technique and exact linearization. In addition, it employs disturbance compensating mechanics to control the system to follow a linear reference model which has pole place...
This paper presents the application of Hilbert transform and artificial neural network (ANN) for power quality (PQ) disturbance classification. The input features of the ANN are extracted from the envelope of the disturbance signals by applying Hilbert transform (HT). The features obtained from the Hilbert transform are distinct, understandable and immune to noise. These features after normaliz...
Data-driven control based on the fundamental lemma by Willems et al. is frequently considered for deterministic LTI systems subject to measurement noise. However, besides noise, stochastic disturbances might also directly affect dynamics. In this paper, we leverage Polynomial Chaos Expansions (PCE) extend towards systems. This extension allows predict future statistical distributions of inputs ...
Noise disturbance in training data prevents a good approximation of a function by neural networks. To achieve better approximation results we combine neural networks with noise reduction algorithms. We compare different methods to distinguish between samples with high noise level (outliers) in a dataset and samples with low noise level. Drawbacks of common outlier detection approaches are analy...
Sound as a non-visual component of landscape, has a significant impact on individuals perception of space. Because unlike the landscape that seeing and looking is totally an optional action, soundscape regardless of people comes to be heard and understood. Lack of attention to quality of emitted sounds in the environment may leads to problems such as noise pollution, lack of concentration, nois...
PCA based temperature controller was used to control Ethanol concentration produced in Yeast fermentation process. The controller was designed at a specific operating point and its disturbance rejection performances were studied. Substrate inlet temperature proved to be the most significant disturbance input from the analysis of open loop responses. Q-statistic (SPE) of process measurements con...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
The objective of this contribution is to discuss three basic control design methods for disturbance rejection. The key idea is to use a simple fixed continuous time noise model as a design variable to specify the desirable closed loop properties, e.g., the closed loop bandwidth. We will study three closely related controller design methods based on the noise model, namely minimum variance contr...
Possible adverse health effects due to exposure of wind turbine noise have been discussed since the first modern electrical generating wind turbines were erected in the 1970’s. Despite this, only a few large epidemiological studies have been carried out. This paper is based on data from two Swedish studies and one Dutch study in which self-reported health and well-being were related to calculat...
Undisturbed sleep is essential for physiological and psychological health. Children have a special need for uninterrupted sleep for growth and cognitive development. Noise is an environmental factor that affects most children, but the knowledge of how children's health, wellbeing and cognitive development are affected by noise disturbed sleep due to road traffic is very incomplete. It has been ...
