The Research Of Pmsm Servo System Based On Irmck201

PMSM servo system has become the mainstream of AC servo system now, for its easy-control, fast response, high efficiency and cheaper price. Its controller realizes motor control by DSP in software. There are some AC servo motor control ICs appearing aboard in recent years, which base on FPGA platform and realize motor control algorithm in hardware.They can make up servo control system easilier than DSP. This dissertation takes PMSM as the controlled object, and introduces a design of PMSM servo system based on IRMCK201. The results of the simulation and experiment upon it are presented.Firstly, a brief introduction upon the development progress of permanent magnet AC servo system and a comparison between the two mainly control strategy- Direct Torque Control (DTC) and Field-Orientation Vector Control (FOC)are presented. And then the prospect of permanent magnet AC servo system and the new design idea such as IRMCK201 are analyzed based on an overall review of related papers published recently.Based on the mathematical model of PMSM,Advantages of the rotor field-orientation vector control of id = 0 are summarized.After some theoretical researchs on the flux-weakening control strategy of PMSM,we conclude that interior PMSMs are more suitable for flux-weakening control than surface PMSMs. The numeral SVPWM algorithm and the simplest control model of the servo system are given. The simulation based on Matlab/Simulink is analyzed.The hardware and software design of PMSM servo systems based on TI DSP TMS320LF2407A and IRMCK201 chips are described thoroughly. The meanings and configure methods of the registers in IRMCK201 are given in detail. Finally, the experiment is accomplished in the non-load conditions, and its results are analyzed.
