ACCA : Automatic Control and Computer Architectures

Specification of application Specification of target Specification of environment

The research activities of ACCA are situated in four domains, all centred around the industrial employment of advanced computer architectures: 1) ACCA is specialised in the development of system level design tools for the real-time prototyping and implementation of heterogeneous digital signal processing (DSP) systems. With these tools, it also implements DSP applications for third parties on c...

Robust Takagi-Sugeno sensor fault tolerant control strategy for nonlinear system

A New CFAR Detector based on Automatic Censoring Cell Averaging and Cell Averaging

In order to improve the interference immunity of the detector, a new CFAR detector (ACGCACFAR) based on automatic censoring cell averaging (ACCA) and cell averaging (CA) is presented in this paper. It takes the greatest value of ACCA and CA local estimation as the noise power estimation. Under swerling II assumption, the analytic expressions of fa P in homogeneous background are derived. In con...

An Efficient Implementation of Automatic Cloud Cover Assessment (ACCA) on a Reconfigurable Computer

Clouds have a critical role in many studies, e.g. weatherand climate-related studies. However, they represent a source of errors in many applications, and the presence of cloud contamination can hinder the use of satellite data. This requires a cloud detection process to mask out cloudy pixels from further processing. The trend for remote sensing satellite missions has always been towards small...

Design of Fuzzy Logic Based PI Controller for DFIG-based Wind Farm Aimed at Automatic Generation Control in an Interconnected Two Area Power System

This paper addresses the design procedure of a fuzzy logic-based adaptive approach for DFIGs to enhance automatic generation control (AGC) capabilities and provide better dynamic responses in multi-area power systems. In doing so, a proportional-integral (PI) controller is employed in DFIG structure to control the governor speed of wind turbine. At the first stage, the adjustable parameters of ...
