说明：  神经网络PID的响应速度比常规PID控制要快，而且系统的调整时间很短，能很快达到给定值，系统输出没有超调，并且误差减小的速度也比常规PID快，因此说明神经网络PID的控制效果要优于常规PID控制。
(PID neural network response speed faster than the conventional PID control, and adjust the system time is very short, can quickly reach a given value, the system output does not overshoot, and the speed error decreases faster than the conventional PID, so the description of nerve network PID control performance is superior to conventional PID control.)
