nowadays, the use of intelligent control systems to reduce human error is one of the most popularresearch fields. design and implementation of such controllers requires to actual knowledge of theenvironment conditions. traffic lights as one of the inputs of intelligent control systems are significant.usually the traffic lights have the various physical structure. also, generally in image proces...

Many researches have focused on the optimal design of tuned mass damper (TMD) system without the effect of soil–structure interaction (SSI), so that ignoring the effect of SSI may lead to an undesirable and unrealistic design of TMD. Furthermore, many optimization criteria have been proposed for the optinal design of the TMD system. Hence, the main aim of this study is to compare different opti...

In this paper, a fixed-structure Individual Pitch Control (IPC) design method for two-bladed wind turbines is presented. IPC is an active load reduction technique designed to lower wind turbine loads, which are caused by continuously varying wind conditions. Based on load measurements, the once-per-revolution (1P) loads and harmonics of this frequency (2P, 3P, etc.) can be reduced by rotating (...

A systematic control structure design method is applied on the concentric heatintegrated distillation column (HIDiC) separating benzene and toluene. A degrees of freedom analysis is provided for identifying potential manipulated and controlled variables. Optimal operation is mapped and active constraints are identified for constructing the supervisory control layer. The fundamental problem of o...

A model-based approach to design a robust fault tolerant control of a mobile structure is studied. The method considers the application of robust control techniques to integrate the control design and the fault diagnosis. The main purpose of this approach is to design a robust controller insensitive to the effects of faults and a fault detector filter. This approach is applied to a particular u...

In the design of the control system, the plant perturbations and the plant uncertainties could cause the performance degradation and/or destabilization of the control system. The H∞ control synthesis and the μ synthesis are well known as the suitable controller syntheses for the plant with the large plant perturbations and/or the plant uncertainties (Zhou & Doyle, 1998), and many successful app...

This study aimed at investigating the impact of writing on Iranian EFL college students’ rhetorical organization. Thirty Iranian female undergraduate students majoring in English at Al-zahra University participated in the current study. The writing instructions included two stages, each lasting for four weeks. The participants were assigned to a control group and an experimental group according...
