His current research is in control engineering, computer controlled systems, hybrid control systems, real-time systems, artificial intelligence, and mechatronics. He has introduced simplified engineering design methods of fuzzy-logic PI/PD, PID, and PIDD controllers. He is also coauthor of two books: “Two-Degrees of Freedom Robust PID Control in Practice,” Polish, in 2006, and “Programmable Automation Controllers PAC,” in Polish, in 2007. He teaches courses in embedded control systems, hybrid control systems, and programmable automation controllers, as well as PLCs and digital control of intelligent servodrives (digital motion control).
