Design and implementation of a PMSM servo drive system applied to intelligent patrol robots

With the intelligent patrol robots become popular used in industrial places, the demands of their motor drive systems become much higher, especially in performance, efficiency and cost. In this paper, a permanent magnet synchronous motor (PMSM) servo drive system applied to intelligent patrol robots is designed. The motor drive system hardware circuit design is realized, and the software programming is based on the field orientated control (FOC) algorithm. The theory analysis and simulation are both carried out in this paper to evaluate the feasibility and performance of FOC algorithm used in the special hardware topology, and the experiment is also carried out to test the PMSM servo drive system performance. Both the simulation and experimental results shows the PMSM servo drive system has great dynamic and smooth performance.
