A Novel Circuit forThermocouple Signals Linearization Using AD Converter

By Ayman A. Aly Aly S. Abo El-Lail

DOI: https://doi.org/10.5815/ijitcs.2013.03.07, Pub. Date: 8 Feb. 2013

A novel circuit for linearization of thermocouple signals using Analog – to – Digital converter (ADC) is proposed. The present method utilizes the ratio metric property of ADCs and the converter performs analog to digital conversion as well as linearization. The resulting circuit also has provision for scaling the linearized digital output to obtain a desired full-scale value. Computational studies carried out on the proposed method gives satisfactory results for thermocouples with monotonic concave upward and downward characteristics.

Intelligent PI Fuzzy Control of An Electro Hydraulic Manipulator

By Ayman A. Aly Aly S. Abo El-Lail Kamel A. Shoush Farhan A. Salem

DOI: https://doi.org/10.5815/ijisa.2012.07.06, Pub. Date: 8 Jun. 2012

The development of a fuzzy-logic controller for a class of industrial hydraulic manipulator is described. The main element of the controller is a PI-type fuzzy control technique which utilizes a simple set of membership functions and rules to meet the basic control requirements of such robots. Using the triangle shaped membership function, the position of the servocylinder was successfully controlled. When the system parameter is altered, the control algorithm is shown to be robust and more faster compared to the traditional PID controller. The robustness and tracking ability of the controller were demonstrated through simulations.
