This paper focuses on a novel command generator for servo-motor drives to be used as an integral part of their motion controllers. The method, which incorporates a new data compression algorithm, is capable of generating trajectory data at variable rates. In this paradigm, higher-order differences of a given trajectory (i.e. position) are first computed and thus the resulting data are compressed via the proposed technique. The generation of the commands is carried out according to the feedrate (i.e. the speed along the trajectory) set by the external logic dynamically. The paper discusses the implementation of the method on a Field Programmable Gate Array (FPGA). During implementation Very High Speed Integrated Circuit Hardware Description Language (VHDL) is used rather than using embedded processors on the FPGA chip. The performance of the method is assessed according to the resources used in the FPGA chip on the development board and these results are also compared with the same approach without an interpolator.

Direct command generation for CNC machinery based on data compression techniques Yaman, Ulaş; Dölen, Melik (2013-04-01) This paper presents a direct command generation technique for digital motion control systems. In this paradigm, higher-order differences of a given trajectory (i.e. position) are calculated and the resulting sequence is compacted via data compression techniques. The overall method is capable of generating trajectory data at variable rates in forward- and reverse-directions with the utilization of a linear interpolator. As a part of the command generation scheme, the paper also proposes a new data compressio...
A monolithic phased array using rf mems technology Topallı, Kağan; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2007) This thesis presents a novel monolithic phased array implemented using the RF MEMS technology. The structure, which is designed at 15 GHz, consists of four linearly placed microstrip patch antennas, 3-bit distributed RF MEMS low-loss phase shifters, and a corporate feed network. The RF MEMS phase shifter employed in the system consists of three sections with a total of 28 unit cells, and it occupies an area of 22.4 mm 2.1 mm. The performance of the phase shifters is improved using high-Q metal-air-metal ca...
A Simple Sliding Mode Controller for PUC7 Grid-Connected Inverter Using A look-up Table Makhamreh, Hamza; Trabelsi, Mohamed; Kuekrer, Osman; Abu-Rub, Haitham (2019-01-01) In this paper, a novel and simple controller for seven-level packed U-cell (PUC) grid-connected inverter is presented. The control method is derived based on sliding mode control theory. Making use of the measured grid voltage and computed reference grid current, the reference value of the inverter output voltage is determined. According to the calculated voltage value, the suitable control set is selected (offline) in order to satisfy the reaching conditions of two separate sliding lines. The sliding lines...
A New Micro fabrication Process Simulator for MEMS Designs YILDIRIM, ALPER; Dölen, Melik (2008-01-01) This paper introduces a new process simulator for micro-electro-mechanical systems. The open-source program, which has been developed via C/C+ + language along with the OpenGL library functions, significantly speeds up the design phase by providing realistic outcomes about the micro-fabrication processes involved. While anisotropic/isotropic etching of silicon wafers are of major interest, the developed software can conveniently simulate additive micro-fabrication processes such as doping and material depos...
