In this work we propose a high performance elliptic curve cryptographic processor over GF(2) for the applications that require high performance. It has three finite field (FF) RISC cores and a main controller to achieve instruction-level parallelism (ILP) for elliptic curve point multiplication. Customized instructions are proposed to decrease clock cycles. The interconnection among three FF co...

This paper discussed about proposes an architecture and implementation of a controller via Function Block Development Kit (FBDK). It can be used to create an open CNC architecture on ISO 14649 and Function Block (IEC 61499). This offers interoperability, portability, and adaptability. The system framework consists of three main components: (1) STEP-NC Parser, (2) Tool Path Simulator, and (3) Co...

This paper presents an investigation into the design of a flight control system, using a robust backstepping control structure, designed using the two-time scale control procedure of the dynamic of a small-size autonomous helicopter in hover. The two-time scale controller takes advantage of the ‘decoupling’ of the translational and rotational dynamics of the rigid body, resulting in a two-level...

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,...

In this paper we propose a model based on the Model-View-Controller design paradigm and built over the integration of open source frameworks, which are widely supported by the software architect community. The main contribution of this model lies in that it provides a true decoupling of the MVC paradigm’s model, view and controller elements. This approach eases the horizontal development and ma...

One of foremost problems in stand-alone photovoltaic systems consists on the election of a strategy for charge controllers. The charge controllers main function is the accumulation system protection, and this leads to an extension of the batteries lifetime, thus reducing, the long term economic cost of the installation. This document describes a Fuzzy Logic based charge controller. In order to ...

This article introduces a novel distributed controller approach for networked control systems (NCS) to achieve finite gain L2 stability independent of constant time delay. The distributed controller is alternatively interpreted as a linear transformation of the inputoutput space of the controller and the plant, and in fact represents a generalization of the well-known scattering transformation....

this paper investigates the use of self learning fuzzy PD controller applied to SVC device for improving damping inter-area modes of oscillations. The SLFLC utilizes sensitivity model for learning of SLFLC parameters. This has been enhanced by adding an integral term whose gain coefficient is also synthesized by learning that is actuated after completion of the main learning algorithm. The pape...

This paper presents a method for designing of proportional-integral-derivative (PID) controller based on unified power flow controller (UPFC) using chaotic harmony search algorithm (CHS) for damping of low frequency oscillations (LFO) in a power system. The main aim of this paper, optimization of selected gains with the time domainbased objective function which is solved by chaotic harmony sear...

Focuses on the benchmark control problems for seismically excited nonlinear buildings defined by Ohtori et al. (2000). This benchmark study focuses on three typical steel structures, 3-, 9and 20-storey buildings designed for the SAC project for Los Angeles in the California region. The first stage of applying the fuzzy controller to this benchmark study for the 3-storey building is reported. Th...
