Study On The Experiment System For Computer Control Technique Course Based On DSP

The application of computer control system in industry process becomes more and more widespread. And that may need the technicians who do the related works have to obtain the special knowledges and techniques like theory and strategy of control, data communication, hardware and software design of computer control system. So computer control system has been picked as a required course for the students who are major in information automation, computer application, electronic and electrical engineering in many universities and colleges. In order to make the students have more deeply and clearly understand about the structure and function of the computer control system, it is necessary to provide some experiments according to the schedule of course. Besides, as DSP has been used in industry control systems and commercial or civil electric devices more and more regularly, to know about the principle of DSP and how to design and debug DSP system is one of the most important techniques which should be obtained by the technicians in the related fields.Because of the practical needs presented above, the main purpose of this topic is to provide an experiment system for students who have computer control technique courses based on DSP. The main function of the experiment system is to control the model that is a DC motor in this system by PID control after identifying the model. And users could observe the different results of the control method by changing the control parameters. So they could got a profound understand for this control method and the usage of the parameters. At the same time, Fuzzy control and Fuzzy-PID control emulation have been made according to the identified motor model by Matlab, and the different results of these methods have been analyzed.In hardware design, the TMS320F2812 DSP is the core CPU of this system that accomplished the control of the DC motor. Besides, some peripheral interfaces are extended. So the system could be an experiment board for DSP system designing as well. In software design, the experiment board applies the CCS development platform and C language to realize the functions. With Windows XP system, Visual Basic language is used to develop the operation interface for the users.
