Summary: Structures of AC electrical drives with vector controlled induction motor. Control of permanent magnet synchronous motors and electronically commutated motors. Degree of complexity of mathematical models taking into consideration the type of drive application (position control, kind of load). Parameter identification - estimation. Multiprocessor control, adaptive and optimal algorithms. Multi - axis electrical drives. Thermal models of power semiconductor devices, calculation and computer controlled measurement of transient thermal response.

Keywords: automatic control, AC electrical drives, induction motor, permanent magnet synchronous motor, electronically commutated motor, vector control, estimation, inverters, power semiconductor device, thermal model

Research goals: Elaboration of theoretical foundations and algorithms of the analysis and synthesis-design of controlled electrical drives with vector controlled induction motors and permanent magnet synchronous motors-electronically commutated motors. Establishment of appropriate methods of identification and variables estimation of the semiconductor inverter-machine whole. Establishment and optimizing of speed and position control systems' structures, taking into consideration the demands in the domain of NC machine-tools, flexible automation, industrial robots, fast elevators. Methods of synthesis-design of multi-axis servomechanisms. Methods of determination and improvement of power performances, protection concepts and diagnostics of AC electrical drives. Elaboration of thermal models of power semiconductor switches. Among other things, several MSc and PhD degrees will be gained.
