Design and Implementation of AC Permanent Synchronous Motor Controller

An introduction on the vector control principle is provided. And uses the TI digital signal processor TMS320F2811 to design the Three Phases Permanent Synchronous Motor Controller based on the Space Vector Pulse Width Modulation Arithmetic. The design divides into the hardware part and the software part. The hardware part detailed describes the design scheme of the hardware system and pro- vides diagrams of the eneoder circuit, current detecting circuit and the current foldback circuit. The software part introduces the design and implementation of the Space Vector Control Arithmetic, and gives detailed instructions on the arithmetic of the circuit loop and the speed loop. Practice on the real motor proves that the system is accurate, sensitive and coincides with design requirements.
