针对目前自动称重配料系统中采用传统PID控制的不足、系统误差不稳定、动态特性不理想，提出了一种基于神经网络PID控制的算法。该系统传递函数为 ,本文设计BP神经网络为三层，输入层4个节点,隐层为5个节点，输出层为3个节点。-For automatic weighing batching system currently used in traditional PID control deficiencies, systematic errors unstable dynamics is not

采用单纯型法辨识传递函数的参数低isjdiajd -identity function

预测控制仿真程序，方法为广义预测，对象基于传递函数-Predictive control simulation program, the method is generalized to predict, based on the transfer function of the object
