Much of the research is related to measurement, control and signal processing, mainly considering applications in mechatronic, industrial, and robotic systems. A particular focus has been on the development of new digital tachometers for use in closed-loop control servo-systems and open loop measurement systems. These systems intrinsically involve the signal processing of quantized signals and work on these sensor-based measurement systems has been generalized to the analysis of the errors associated with DSP filters, when processing quantized signals. The visualization of robotic mechatronic and energy systems through the use of virtual reality software is a related area of active research.
