Optimum Design for a Combined Speed Control Hump and Pedestrian Crossing.

Design and Simulation of Double Loop Control for Power Converter Fed Variable Speed DC Drive

Design and PLC Implementation for Speed Control of DC Motor using Fuzzy Logic

In this article, a speed control of DC motor is designed and illustrated using fuzzy logic-based programmable logic controller (PLC). The DC motor is an attractive part of electrical equipment in many industrial applications requiring variable speed and load specifications due to its ease of controllability. The designed system is consisted of three main parts including programmable logic contr...

Optimum Feedback Amplifier Design For Control Systems

Many designers think of control system feedback loop compensation only in terms of stable or unstable. In reality, there is an optimum error amplifier transfer function for any given loop crossover frequency and phase margin. The optimum design is shown to be the one with the highest gain below crossover and the lowest gain above crossover. There is a unique pole-zero placement to achieve optim...

A Combined Fuzzy Logic and Analytical Hierarchy Process Method for Optimal Selection and Locating of Pedestrian Crosswalks

One of the main challenges for transportation engineers is the consideration of pedestrian safety as the most vulnerable aspect of the transport system. In many countries around the world, a large number of accidents recorded by the police are composed of accidents involving pedestrians and vehicles, for example when pedestrians may be struck by passing vehicles when crossing the street. Carefu...

A New Algorithm for Optimum Voltage and Reactive Power Control for Minimizing Transmission Lines Losses

Reactive power dispatch for voltage profile modification has been of interest Abstract to powerr utilities. Usually local bus voltages can be altered by changing generator voltages, reactive shunts, ULTC transformers and SVCs. Determination of optimum values for control parameters, however, is not simple for modern power system networks. Heuristic and rather intelligent algorithms have to be so...
