Under the research context of two axis digital control turntable, this paper has set up a mathematical model of control system of turntables. Proceeding from such model, it has made an analysis on the deficiencies of classical PID control during turntable control. Against the feature of PID parameters difficult to be tuned, the neural network is thus introduced in the optimizing process of turncontrol PID parameters, during which PID controller is designed based on BP network. In addition, the PID algorithm control based on BP network is simulated with results indicating PID controller designed so featuring high tracking accuracy, stable performance and strong robustness, which provides a solution to the problem of inadequate precision required by classic PID control as regards to the control precision.
