The control system improvements of a linear high anisotropy reluctance servo-drive are presented in the paper. The drive is position controlled and consists of a high thrust developing linear actuator supplied by a MOSFET converter. The early version of the system was provided by current and position loops. In the paper the control system is improved by implementing a speed loop also. The signal speed is obtained by properly filtering the position signal time derivative outputted by a potentiometric transducer. Simulation and experimental results executed on a prototype drive are presented to highlight the drive performance improvements.

Abstract
The control system improvements of a linear high anisotropy reluctance servo-drive are presented in the paper. The drive is position controlled and consists of a high thrust developing linear actuator supplied by a MOSFET converter. The early version of the system was provided by current and position loops. In the paper the control system is improved by implementing a speed loop also. The signal speed is obtained by properly filtering the position signal time derivative outputted by a potentiometric transducer. Simulation and experimental results executed on a prototype drive are presented to highlight the drive performance improvements.
