Dc Motor Controlling System

Does anybody know any DC motor controlling systems which can control a rotation speed of the direct current motor?

virtually all industrial controllers for DC motors will control the speed of the motor.
In open loop mode, the controllers are controlling the torque, however by using either a tacho, or armature feedback to indicate speed, they use the torque control to control the speed. Too slow, increase the torque, too fast, reduce the torque.

the controlling on the speed of dc machines is divided in to two ways
firstly , controlling on the speed through AC voltage and this method is used with motors that in constant location
secondly , controlling on the speed through PLC device , and this method is used with motors that in variable location like truction motors
