If you look here at the pic you will see that the pic is a current controller schematic, it might work but I guess you need to add a speed differential -> currentReference opamp circuit. And also I do not spot the motor inductance compensation circuit, so the current might hunt a bit and heat up the motor if you are unlucky.
So all in all it gets complicated (cant be built with a torque wrench) http://www.national.com/pf/LM/LMD18200.html#Overview I googled a bit and I found this link: http://www.wegatech.com/motor_controller.html you might be lucky. it came from this page: http://www.opencircuits.com/Motor_driver there is lots of stuff there. Just page through there might be more. j.
