Abstract: In many industrial applications like semiconductor production and optical inspection systems, the availability of positioning systems capable to follow trajectory paths in the range of several centimetres, featuring at the same time a nanometre-range precision, is demanding. Pure piezoelectric stages and standard positioning systems with motor and spindle are not able to meet such req...

Recent years have witnessed an exponential growth in the complexity and performance of field-programmable gate arrays (FPGAs). This has lead to high adoption of FPGAs in embedded applications, such as consumer electronics, medical devices, and microelectromechanical system. Due to the FPGAs attractive features, choosing FPGAs as a control systems deployment platform is also spreading. This pape...

An intelligent control scheme using a fuzzy switching mechanism, grey prediction and genetic algorithm (GA) is applied to a coupled nonlinear system, called a twin rotor multi-input multi-output system (TRMS). In real-time control, a Xilinx Spartan II SP200 FPGA (Field Programmable Gate Array) is employed to construct a hardware-in-the-loop system through writing VHDL on this FPGA. The objectiv...

We report the development of an instrumentation and control system instantiated on a microprocessor-field programmable gate array (FPGA) device for a harmonic oscillator comprising a portion of a magnetic resonance force microscope.
