How can i run a BLDC motor continuously and control the speed of it in a easy and primitive way?

i know,just by applying power,a BLDC wont rotate like normal DC motors,but they need some kind of electronic controller to switch on one set of coils and another set alternatively to rotate the rotor and the voltage applied to those coils determines the speed of the motor..

But what i want is a BLDC motor to run continuously and i should be able to control its RPM from very low to max...
is there any way to achieve this like some specially made IC's for BLDC control or any other?
 

Brushless motor controller can be implemented using a microcontroller, or may alternatively be implemented in analogue hardware or digital firmware using an FPGA. If you want to know more you can refer to Microchip's AN857 Application Note. Here's a basic circuit.
