Efficient DC motor control

Hi everyone,

I have to develop a PMDC motor control. The main requirement is the 

maximum possible efficiency

. Since I'm interested in a one way rotational direction, I thought that a low-side control (chopper) could be a good choice. Am I right? 

System specification:

- 200W PMDC motor; 

-10A maximum current;

-30V supply voltage.

Even if I know how to lay down a basic design of a low-side control, I have no experience about choosing components. So, my question is: which MOS, MOS driver and freewheeling diode should I choose to achieve the highest possible efficiency?

Are there any other tricks for the efficiency sake?

Thanks in advance
