【Abstract】 The design of digital servo system for turntable and its realization are introduced. In the design, the digital signal processor (DSP) and complex programmable logical device (CPLD) are used to efficiently decreases the influence of inherent factors in analog circuit, such as noise and excursion, and greatly increase the accuracy of the system. The practicability and effectiveness of the scheme are illustrated by experiments.更多还原
