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 high thrust developing linear actuator supplied by MOSFET converter. The early version of the system was provided by current and position loops. In the present 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 high thrust developing linear actuator supplied by MOSFET converter. The early version of the system was provided by current and position loops. In the present 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
