Universal Approach to Implementation of Three-Phase Induction Motor Control Algorithms Using Microcontrollers: Preliminary Results

This paper describes process of building a universal digital system to control commonly used three-phase asynchronous motors. Considerable effort was devoted to a universal approach, which will allow further extension of the system with advanced algorithms and also the use of other control units. A test bench was designed and created with an interface board connecting all the components. The system includes two programs: a motor controller and a graphical user interface controller. The created system allows controlling the motor without being connected to a personal computer and operates a power bridge evaluation board and an industrial inverter installed in the test bench. Prepared control structure provide possibility to fast change of algorithm. Preliminary results of real experiments are demonstrated for real two example processes. Further development of the system including advanced control algorithms was also indicated.
