Self-stabilizing algorithms must fulfill two requirements generally called closure and convergence. We are interested in the convergence property and discuss a new method on proving it. Usually, proving the convergence of selfstabilizing algorithms requires a well-foundedness argument: briefly spoken, it involves exhibiting a convergence function which is shown to decrease with every transition...

For the electric steering gear control systems, the principle of the system is introduced. Specific model and parameters are selected to deduce the optimal combination of control system and choices method of the steering system model is determined. The transfer function of motor according to the parameters is achieved and simulation results are gained based on MATLAB. Simulation results show th...

Abstract – 2 H design of decoupled control systems is treated in the generalized plant model. The existence condition of a decoupling controller is stated and a parameterized form of all achievable decoupled closed loop transfer matrices is presented by using the directional interpolation approaches under the assumption of simple transmission zeros. The class of all decoupling controllers that ...

The simple repetitive control system proposed by Yamada et al. is a type of servomechanism for periodic reference input. Thus, the simple repetitive control system follows a periodic reference input with small steady-state error, even if there is periodic disturbance or uncertainty in the plant. In addition, simple repetitive control systems ensure that transfer functions from the periodic refe...

The LMS (Least-Mean-Square) algorithm, which can obtain the complex transfer function in real-time, allows the changes of noise characteristics and the environment of system, thereby maintaining the convergence performance. Therefore, many algorithms based on the LMS algorithm have been modified to solve for some practical considerations, and the FXLMS (Filtered-X LMS) algorithm has been widely...

The speed control performance improvement of a detuned indirect field-oriented (IFO) induction motor drive is studied. First, the dynamic behaviour of a detuned IF0 induction motor drive is observed, and its transfer function model is established. Then a proportional plus integralderivative (PI-D) two-degree-of-freedom controller (2DOFC) is designed for an ideal I F 0 induction motor drive for ...

This paper presents a new control-loop configuration criterion for multivariable processes. Both the steady-state and transient information of the process transfer function are investigated. A new interaction measurement, relative normalized gain array, is proposed for evaluating control-loop interactions. Consequently, a new loop pairing criterion based on the relative normalized gain array is...

Existing large industrial control systems often exhibit poor tracking and disturbance rejection capabilities due to a large number of decentralized control loops. To improve these, a stabilizer design procedure is proposed based on H∞ optimization. The procedure is simple to apply and requires only some of the closed-loop transfer functions. Application of the approach in the Syncrude utility p...

This document specifies a set of methods, headers, message bodies, properties, and reports that define Access Control extensions to the WebDAV Distributed Authoring Protocol. This protocol permits a client to read and modify access control lists that instruct a server whether to allow or deny operations upon a resource (such as HyperText Transfer Protocol (HTTP) method invocations) by a given p...

A power system always contains parametric uncertainties. In the design of a controller the uncertainties have to be considered. Otherwise, if the real plant differs from the assumed plant model, a controller, designed based on classical controller design approaches, may not ensure the stability of the overall system. In this paper design of robust control for the UPFC controllers including powe...
