Yes, but of course it depends on application. Generally SRM is pulse driven machine so counting the numer of pulses You know the position of the rotor. The rotor position angle change on a single pusle of 2*Pi/(m*Zr), where: m- is a number of phases of stator windings and Zr - is a number of rotor's teeth. The torque is weaker then in comparable PMDC motor but You can apply PM Switch Reluctance machine and have higher torque from the same size of the motor. Also the speed  is easy to control and in effect in my opinion SRM is quite applicable for servo drives.
