Abstract


Servo System is a sort of advanced control systems,whose output can respond the external input rapidly and accurately.Servo systems are ever-increasingly utiized in many fields,including industrial controllers,household appliances and Aeronautics and Astronautics. Modern industrial manufacturing requires more excellent performance of servo equipments, therefore,it is quite important to study and develop AC servo system with high performance and high reliability.In the field of servo,In the structure characteristic and operation,the permanent magnet synchronous motor is more outstanding performance and broader scope than other types of traditional servo motor.Permanent Magnet Synchronous Motot(PMSM) is applied more and more in AC servo system.Digital controlled AC servo systems will be the trend,which uses Permanent Magnet Synchronous Motors(PMSM) as power units and high quality control strategy,based on DSP.Based on the research of operation theory of the PMSM,the details of the field-orientation vector control theory are presented in this paper,the i_d=0 scheme and the Space Vector Pulse Width Modulation(SVPWM) method is chosen.The digital signal processor(DSP) TMS320LF2407 made by TI Company is adopted as core of the control system in this paper.A full-digital PMSM servo system is developed based on DSP.The design and debugging of all of the control system circuits and periphery assistant circuits is also explained,including the power driving circuit,the power supply circuit and the sensor circuit etc.The software,programmed by Assembly program under the CCStudio2.2 Integrated Development Environment(IDE) provided by TI Company,Complete the main program modules and subroutine module design,Realizing the current A/D sampling, Switching model,speed PI adjuster,etc.Two close loop vector control with feedback of position,speed and current are realized.The flow charts of main program and Each subroutine module are given in the paper.The experimental results show that the servo control system designed in this thesis has the response speed,small over-correction,speed,torque,wide range of speed etc,has good dynamic and static characteristic and high precision,so it achieves the expectative effect basically.Prove the feasibility of the design of the system.
