Course detail
FEKT-MPC-MRPAcad. year: 2024/2025
The course discusses modern microprocessor circuits and their use in electric drives with feedback control. The STM32 microcontroller with ARM core is used in the laboratory exercises to demonstrate the subject. In the laboratory exercises, the students are introduced to the Nucleo development platform, on which they implement simple tasks to learn about the architecture and peripherals of microcontrollers for electric drives (DSP instructions, A/D converter, pulse-width modulation generator, timers, etc.) and also control loop algorithms are implemented on a real laboratory drive.
