[Abstract]:Servo system is the result of the combination of motor manufacturing technology, detection technology, power electronics technology, microprocessor technology and modern control technology. PMSM has the advantages of high efficiency, high torque / current ratio and low inertia, etc. With the support of high performance microprocessor chip and advanced control theory, permanent magnet synchronous motor (PMSM) is widely used in servo control field. Taking the most advanced digital signal processor chip TMS320F2812 as the core control unit, this paper attempts to design a permanent magnet synchronous motor servo system, and makes theoretical research and practical exploration on some key links. First of all, combined with the literature, this paper comprehensively describes and summarizes the current AC motor servo system involved in the key technologies and development status, and then the AC permanent magnet synchronous servo system control technology is briefly introduced. The research content and working arrangement of this paper are put forward. Secondly, the work and control principle of PMSM are summarized, the principle of vector control is expounded, and the weak magnetic field control method based on the minimum terminal voltage ratio is put forward in view of the characteristic that the speed range of the common control method is not wide. Combined with space vector pulse width modulation, the control scheme of permanent magnet synchronous servo system is proposed. Thirdly, using TMS320F2812 as the core controller to try to design and develop a motor servo platform based on DSP. The SVPWM space vector pulse width modulation technique is used to realize the field-oriented vector control, in which the main circuit is a typical two-point three-phase intersecting one alternating voltage source inverter. The intelligent power module (IPM) is used as the main switching device of the inverter, and the design of the hardware and software of the control system is also studied. Finally, the simulation of the system is carried out to further verify and deepen some theoretical results obtained above.
