The Servo System Design And Implementation

Servo system has been applied in many domains. Its essential role lies in executing the instructions from upper control system, so as to realize the exact track to the position expected. In this dissertation, a two-dimensional digital servo system based on TMS320LF2407ADSP was designed and implemented for image tracking or IMU testing.In my dissertation, the composing and theory of servo system was elaborated, and set up the mathematics model of whole system, then completed dynamic analysis and the simulation of it.On the base of the simulation, the software and hardware of servo system were designed. Hardware included signal generator of resolver transmitter, resolver-digital transmitter, the driver of the signal from DSP which used to control the motor. Software included getting of the coarse and fine code and Combining of them, the digital PID controller, outputting of PWM.Finally, based on the software and hardware, joined with the arithmetic of PID and adjust the parameter of PID. From the ultimate analysis, it was approved that the system satisfied the request.
