Opis:: This paper presents an inductive Contactless Power Supply (CPS) system for robots and manipulators. The energy is transmitted using rotatable transformer with adjustable air gap and power converter. To minimize total losses of the system a series resonant circuit is used. It ensures zero current switching (ZVS) condition for MOSFET power transistors. The controller and protection are implemented in FPGA system. The resonant frequency is adjusted by extreme regulator, which follows instantaneous value of primary peak current. Some simulated and experimental results, which illustrate operation of developed 3 kW laboratory model, are presented.

Opis:: Traditionally, control algorithms are designed without a consideration of their real-time implementation details. The performance of a digital control system, besides the sampling period, depends on many variables, such as the control loop execution time, jitter, complexity of the control algorithm etc. In this paper attention is focused on the inter-action of the parameters of the scheduled tasks and on the performance of control loops closed with digital controller. A design approach that is based on the relative speed classification of the control system has been proposed. The approach is illustrated by the analysis of control systems developed for laboratory magnetic levitation process.
