Research ArticleOpen accessIn the keywordsSimulation Analysis on Proportional Integral and Derivative Control of Closed Loop DC Motor Drive with Bipolar Voltage SwitchingP. Karpagavalli, A. Ebenezer JeyakumarThis study presents the performance of a new four quadrant single phase DC drive closed loop system controlled by proportional integral and derivative controller with Pulse Width Modulation (PWM) full bridge DC-DC converter using bipolar voltage switching. The proposed method is found to be more efficient in improving the step response characteristics such as reducing the settling time, rise time, … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 29 Jun 2013 · 6,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractFault Tolerant Control Using Proportional-Integral-Derivative Controller Tuned by Genetic AlgorithmS. Kanthalakshmi, V. ManikandanProblem statement: The growing demand for reliability, maintainability and survivability in industrial processes has drawn significant research in fault detection and fault tolerant control domain. A fault is usually defined as an unexpected change in a system, such as component malfunction and variations in operating condition, which tends to degrade the overall system performance. The purpose of fault detection is … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Self-Tuning Proportional-Integral-Derivative Controller for an Autonomous Underwater Vehicle, Based On Taguchi MethodM. Santhakumar, T. AsokanProblem statement: Conventional Proportional-Integral-Derivative (PID) controllers exhibit moderately good performance once the PID gains are properly tuned. However, when the dynamic characteristics of the system are time dependent or the operating conditions of the system vary, it is necessary to retune the gains to obtain desired performance. This situation has renewed the interest of researchers and practitioners in PID control. … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Controller Design of an Electro-Hydraulic Actuator SystemM. F. Rahmat, S. Md. Rozali, N. Abdul Wahab et al.Problem statement: Electro-hydraulic actuators are widely used in motion control application. Its valve needs to be controlled to determine direction of the motion. Mathematical modeling is a description of a system in terms of equations. It can be divided into two parts; physical modeling and system identification. The objective of this study was to obtain mathematical model of an electro-hydraulic … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 11,183 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMethodical Tuning of Proportional Plus Integral Controllers for Cascade Control of Separately Excited DC MotorsIbrahim Al-AbbasThe cascade control of DC motors by PI controllers was extensively used in industry. Approximation rules based on plotting the output of the system or on computer simulation were used to determine the parameters of these controllers. This study was done to develop mathematical expressions to calculate the parameters of these controllers. Output time functions of the system and there … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 12 Sep 2012 · 7,008 accessesView PDFCite
