Hi All, can someone suggest a book where current and speed controls are well explained?

The Control Techniques Drives & Controls Handbook published by the IET

I don't consider my self an expert, I have read part of these books and you may find the text books below interesting depending on the level of detail that you are looking for:

Didactic and Introductory:
Dynamic Simulations of Electric Machinery: Using MATLAB/SIMULINK

Prentice-Hall PTR 1998, ISBN 0-13-723785-5

Advance control topics:
Vector Control and Dynamics of Ac Drives

Thank you two, Jesus and Bill
