During the 21st century adoption of electric motor for irrigation operation will be much more resulting a sharp rise in demand for electricity. The electricity requirement for planning, design and operation of irrigation and water resources systems is necessary. It is a parameter of prime importance in formulating the policy for distribution of electricity as well as decision making in day by day operation and management of electricity distribution network. The study was done for the year 2010-11.

This article has presented an adaptive fuzzy controller for permanent magnet synchronous motor. The rotor speed estimation based on reduced-order extended kalman filter (reduced-order EKF). The sensor less algorithm controls have implemented by very high speed integrated circuit hardware description language (VHDL). The simulation work is performed by MATLAB/Simulink and ModelSim co-simulation mode. The simulation results shown that the motor’s speed has good dynamic performance and isn’t sensitive to the parameter variations.

To begin chapter 10, basic issues in sensorless control of induction motors are outlined. We then present example flux and speed estimators and observers and describe parameter adaptation and self-conmiissioning pro-cedures. Finally, commercial ASDs with induction motors are reviewed.

Pollution from motor vehicle emissions in Switzerland will continue to decline over the next 25 years despite a projected increase in number of vehicles on the road, according to a forecast issued by Switzerland's environment agency Sept. 3. The study by the Swiss Federal Office for Environment, Forests, and Landscape nevertheless warns that the projected decrease in emissions is less than earlier estimates, prompting the need to examine additional pollution-control measures.
