This paper investigates the use of fractional order operators in conventional model reference adaptive control (MRAC). A fractional adaptive controller is designed based on the use of a fractional-order parameter adjustment rule. Applied in numerical…

This paper is to proposes a fractional order adaptive control scheme design for actuator failure compensation in order to balance of a ball-beam system with redundant actuators. The proposed controller is based on a fractional order sliding surface…

Condition monitoring is an important field that can boost manufacturing processes to produce high quality and more quantities. This work presents the design of new Programmable Logic Controller (PLC) Function Block (FB) dedicated to the instantaneous…

In steelworks, due to the complex nature of operations, systems, procedures and methods always involve a certain amount of risk. It is not possible to eliminate all hazards, so the goal is to eliminate and/or control high and critical potential…

The main objective of this paper is to present the use of D-higraph to perform hazard analysis. D-higraph is a functional modeling technique; it is used to capture the functional and structural aspects of process plants. It presents not only the…

The analysis and evaluation of risks by the LOPA method requires the presence of certain data and information on the various risk evaluation parameters such as, the frequencies of initiating events, the probabilities failures of the security barriers…

In this study, a manipulator robot with two degrees of freedom was controlled by Fuzzy-PI adjust by three meta-heuristic algorithms (Grey wolf optimizer (GWO), Whale Optimization Algorithm (WOA) and Teaching–learning-based optimization (TLBO)). The…

The aim of this paper is to realize high-precision attitude stabilization for roll/yaw axes of flexible communication satellite while attenuate the effects of the elastic vibrations and multiple disturbances such as solar radiation and model…

A humanoid robot is now a reality, which has been very developed. It can do almost all tasks that either the human can do or not as well as the dangerous tasks. The researchers recently develop robots, which can see, smell, smile, speak, touch, walk…

In this paper, the magnitude optimization for the design of two dimensional digital filter is attempted and new design method for a two-dimensional (2-D) recursive digital filter is proposed via appropriate genetical swarm optimization with the…
