The digital controller has quick response, good stability, but the algorithm is complex. The topic uses the AVR single chip microcomputer as control core, using ADC0809 as the ADC, TLC7528 as the digital to analog converter, to design the hardware system of digital controller tester. And with the minimum step as the control objective, the topic designs the algorithm procedure;in order to display the control visually, through the LabWindows/CVI software programming, this paper realized the output of controller through RS-232 sent to the host computer for display waveform comparison function. Finally, the actual test effect of digital controller tester is given, which proves the correctness and reliability of the test system design, and provides a new testing scheme for digital controller de-sign theory.
