Three-Degree-of-Freedom Step Motor Control Strategy Based on DSP

Abstract:

Based on the basic principles of analysis of vector control, given three-degree-of-freedom step motor vector control of software and hardware design based on TMS320F2812 for the control, from the simulation results show that: start and 0.2s faster when the speed reaches a given value, the torque increases instantly, but then resumed, when the speed is close to a given torque value becomes 0; 0.8s torque generated when the transition, 0.03s, the torque is stable at 200N • M, show that the system has a good rapid response capability and steady state performance. Realize the decoupling flux and torque control, which makes asynchronous motor DC motor with the same access to instant-response performance, and improve the control performance and system performance.
