| Electric drives are very important application in the Economic construction, lots of production mechanics need regulate speed for the need of running,producing, transporting and saving energy.Before the eighties of the twentieth century,many devices mostly use DC motor speed regulation system.But because of DC motor's complicated structure,manufacture consuming time,constant maintenance and so on, people try to replace the DC motor speed regulation with AC motor speed regulation. By the development of power electronics,PWM technology,computer control and AC motor control,AC speed regulation system is replacing AC speed regulation system by its many faults such as solidity,safety and so on.Compared to DC motor control system,AC asynchronous motor control system has greater advantage in terms of its cost.As a means of asynchronous motor control system,vector control technology has high control accuracy,good dynamic capability and other advantages.Therefore,the vector control system is developing rapidly in recent years.It has become the best choice in the high-performance AC variable frequency speed control system.Vector control of AC motor technology is based on the mathematical model of induction motors,which controls the flux and torque separately by decoupling of excitation components and current components,making the performance of asynchronous motor similar to DC motor.In recent years,the rapid development of high-performance processors, especially the widely application of digital signal processor(DSP),it gradually promotes the vector control technology into practical use.In this paper,a double-loop Vector Control System Solution based on digital signal processor is offered,using the TI TMS320F2808 processor as a control core and IGBT inverter power as module unit,designing a system hardware solution and a software solution.Theoretical analysis and simulation studies have shown that the system has good advantages in its low cost,high precision and dynamic control.
