Design and Implementation of the Control System for a 2 kHz Rotary Fast Tool Servo
The design and development of the control system involved a long list of items including: current compensation; tool position compensation; notch filter design and phase stabilizing with an additional pole for a plant with an undamped resonance; adding viscous damping to the fast tool servo; voltage budget for driving real and reactive loads; dealing with unwanted oscillators; ground loops; dig...
متن کاملCharacterization of Errors Affecting Surface Generation in Fast Tool Servo (fts) Machining
In this paper, a study of the fabrication of optical microstructures by fast tool servo (FTS) machining technology is presented. The study started from locating the sources of error exclusively involved in ultra-precision machining with FTS, which are stroke error, spatial error, trajectory generation error and errors of cutting parameters such as spindle speed, depth of cut, feed rate, etc. He...
متن کاملDesign and Control of a Piezo-based Fast Tool Servo System for Precision Diamond Turning
A novel fast tool servo driven by piezoelectric actuator for precision diamond turning is designed in this paper. To overcome the inherent hysteresis and drift nonlinearity effect of the piezoelectric actuator, a closed-loop control system is established using strain gauge integrated in the actuator for position feedback, which has compact structure and can avoid interference in the machining. ...
متن کاملA Novel Fractional Order Model for the Dynamic Hysteresis of Piezoelectrically Actuated Fast Tool Servo
The main contribution of this paper is the development of a linearized model for describing the dynamic hysteresis behaviors of piezoelectrically actuated fast tool servo (FTS). A linearized hysteresis force model is proposed and mathematically described by a fractional order differential equation. Combining the dynamic modeling of the FTS mechanism, a linearized fractional order dynamic hyster...
متن کاملSliding-mode control of a nonlinear-input system: application to a magnetically levitated fast-tool servo
Magnetic servo levitation (MSL) is currently being investigated as an alternative to drive fast-tool servo systems that could overcome the range limitations inherent to piezoelectric driven devices while operating over a wide bandwidth. To control such systems, a feedback-linearized controller coupled with a Kalman filter has been previously described. Performance limitations that degrade track...
