Research And Development, Dsp-based Dc Servo Motor Control System

This paper designs a system using in DC servo electromotor controlling field based on DSP (digital signal process). Based on the servo system's capability which is more rapidly and more provisioned and more stabilization by request, the paper advances the full-digital aptitude controlling project based on the DC servo electromotor using the TMS320LF2407 produced by TI .Finally, the paper make the control system come true.Firstly, the paper studies the theory of the DSP, especially the theory of the compare operation and the PWM pulse outputting and catch cell. Secondly, the paper studies the theory of the working and configuration of the DC servo electromotor, especially the theory about of the startup, timing and stop of the DC servo electromotor and also studies the PWM control theory and PID theory. Based on the above, the paper designs the DC servo electromotor motion control system using TMS320LF2407 based on the theory of the PWM and the digital PID. In the software environment, the paper designs the software which achieves the functions, such as startup, stop, accelerate and decelerate. The system also achieves the function that the system creates the similar curve based on the parameter inputted by user. In the hardware environment, the paper designs DSP peripheral circuit and drive circuit. And also the paper designs the protect measure.The paper configures the parameter of the speed and displacement PID measure and also defines the parameter of the motor and controller. The software will download the parameters to the object controller.The paper analyses the result of the movement experimentation. The system result is that DC servo motor moves placidity, anchor point nicety, startup quickly, torque wave little and speed controlling agility. It proves that the controlling system designed by this paper is a more perfect system using in the DC servo motor controlling field.Finally, the paper analyses the math model and analyses the dynamic based on the software MATLAB.The paper calculates the parameter and advances the measure of optimizement.
