supply was dc‚ dc motors were used extensively to draw power direct from the dc source. The motor speed could be varied by adjusting field current by a rheostat. That was an open loop control. Most of the drives were constant speed and the characteristics could not be matched with a job requirement. A vast development in the dc drives system took place when the ward Leonard Control System was introduced in the 1980s. The system was motor-generator system to deliver power to the drive motor.

Speed Control of Dc Motor Using Fuzzy Logic Technique 1 1‚ 2‚ 3 J. N. Rai‚ 2Mayank Singhal‚ 3MayankNandwani Department of Electrical Engineering‚ Delhi Technological University Abstract:This project uses FUZZY LOGIC TECHNIQUE in estimating speed and controlling it for DC motor. The rotor speed of the dc motor can be made to follow an arbitrarily selected trajectory. The purpose is to achieve accurate trajectory control of the speed of DC Motor‚ especially when the motor and load parameters

TATA MOTORS—GOING GLOBAL The wave of liberalization‚ privatization and globalization‚ which started sweeping India since the early 1990s‚ gave Tata Motors (established in 1945) a new direction in the path of globalization. The Tata Motors firstly‚ realized that if it wants to grow then it cannot afford to keep its business connected solely to the fortunes of one country. Secondly‚ with the dismantling of import restrictions in the near future or it the rupee begins to gain ground then India may

I. Executive Summary The Ford Motor Company has been facing a steady decline in market share for approximately the past twelve years. This decline is largely attributable to their reputation for building poor quality vehicles that break down easily‚ and rising gas prices reducing demand for large trucks and SUVs‚ which is Ford’s main source of sales. Ford has already taken measures in response to this slump by introducing new car models such as the Fusion‚ as well as attempting to make their
