Course detail

Microcomputer Control of Electrical Drives

FIT-IMTPAcad. year: 2014/2015

In the course, modern microprocessors for electric drives control and their use in electric drives with feedback control are taught. To demonstrate problems, digital signal processor Motorola DSP56800 is used in laboratory practice. In laboratory practice, students work individually with microprocessor development system. There are simple tasks done to meet an architecture and peripheries of microprocessors for electric drives (DSP architecture, A/D converter, pulse-width modulation generator (PWM), timers, etc.), and in next, algorithms of control loop on real electric drive (PSD controller, 1st order higher limiting filter) are done.
