Abstract
In a device having a first member and a second member which are driven relative to one another by an actuator, a servocontrol derives feedback by sensing the torque applied on one of the members by the actuator. The actuator drive signal is modified by a compensation network in response to the torque measurement to provide stability across a bandwidth extending beyond the resonant frequency of the members, thereby providing smooth, accurate and precise motion.
