Vector Control of Permanent Magnet Synchronous Motor

Experimental measurements were conducted to validate the vector control (VC) algorithm's functionality with a synchronous motor (SM). Various scenarios were tested, including start-up, reversal, and responses to speed changes. Stability and regulation quality were assessed under load, with deliberate de-excitation testing to prevent motor damage. Transitioning to torque control, responses to torque changes during start-up and reversal were observed. Despite hardware limitations causing waveform discontinuities, the VC structure proved effective for laboratory purposes. Parameter designs of individual regulators were validated through measured data. The system's capability to handle rapid transients was challenged, necessitating longer recording times on the oscilloscope. Overall, the study confirms the functionality of individual system blocks and the practical feasibility of VC for synchronous drives, highlighting the need to address waveform discontinuities and hardware limitations in future implementations.
