Abstract
In order to improve the problem that the traditional PID control oven controlled crystal oscillator cannot be adjusted in real time in the process of clock taming, a BP neural network tuning PID control algorithm is proposed. BP neural network tuning PID control algorithm can learn the rule of PID control online, and can adjust the parameters of PID control in real time. The results of simulation in MATLAB show that there is no obvious overshoot and oscillation in step response controlled by BP neural network tuning PID, and the system is stable faster than the traditional PID control. Therefore, BP neural network tuning PID control has better control effect than traditional PID control in oven controlled crystal oscillator control, and has a strong self-adaptability in parameter adjustment.
