This p,aper presents a method to analyze the steady-state characteristics of an adaptive notch filter, when the effects of finite precision arithmetic are taken into account. The reduction of these effects by means of error spectrum shaping is also discussed. Closed-form expressions for the steady-state mean square error of variable coefficient have been obtained Finally the results of computer...

Recently, Wang and Landau proposed a new random walk algorithm that can be very efficiently applied to many problems. Subsequently, there has been numerous studies on the algorithm itself and many proposals for improvements were put forward. However, fundamental questions such as what determines the rate of convergence has not been answered. To understand the mechanism behind the Wang-Landau me...

Gross error detection is important to data reconciliation in process industry. In practice, gross errors cannot be identified exactly by any algorithm. The issue of unreasonable solutions of gross error detection algorithms is discussed. A novel mixed integer optimization method presented in a previous paper is used in this paper. A strategy is proposed to identify gross errors and its most pos...

Designing of a PID controller is a very common method for industrial process control and due to its very simple and efficient function; it is used in a wide variety of industrial applications. PID controller to reduce the steady state error and dynamic response of the system is used. PID controller design is an inevitable problem in setting the coefficients need to try a lot of trial and error,...

Wheel loaders are prone to lateral tilting accidents due to their complex working environment, variable structure frame and the large offset of the centroid position. The accidents may seriously threaten the driver’s safety. This paper proposes a steady-state margin (SSM) angle as a new instability threat indicator to analyse lateral stability of wheel loaders. Firstly, the structural character...

We first develop a reduced-rank minimum mean square error (MMSE) detector for direct-sequence (DS) code division multiple access (CDMA) by forcing the linear MMSE detector to lie in a signal subspace of a reduced dimension. While a reduced-rank MMSE detector has lower complexity, it cannot outperform the full-rank MMSE detector. We then concentrate on the blind reduced-rank MMSE detector which ...

In this work we analyze the perfonnance of the newly proposed digital tanlock loop in the presence of additive Gaussian noise. It is shown that the expected value of the steady-state phase errors at the input and the output of the phase error detector are equal to the noise-free steady-state values, while the variance is significantly reduced when the signal-to-noise ratio is increased or the p...

This work presents exact tracking analysis of the ε-normalized least mean square (ε-NLMS) algorithm for circular complex correlated Gaussian input. The analysis is based on the derivation of a closed form expression for the cumulative distribution function (CDF) of random variables of the form [||ui||2D1 ][ε+ ||ui|| 2 D2 ] −1. The CDF is then used to derive the first and second moments of these...

Based on the role of steady state concept in the model of analytical chemical measurement and deduction, the definition of 'practically sleady slate' (PSS) has been inlroduced. The defnition does not require the process to be in steady state in a strictly mathematical sense. In order to fulfil the requiremenls of 'practically steady state' the random error and the syslematic error must vary wit...

Package ”Automatica” is intended for analysis and development of control algorithms for plants, considering parametric and structural uncertainty and influence of unknown-butbounded disturbance. The package is intended for scientists and developers of real-world control systems. The goal of an engineer is to guarantee given steady-state error tolerance for each of the controlled variables while...
