In this design, the use of automatic instrument technology, computer technology and automatic control technology to achieve the level of water tank cascade control. The model of the controlled object is analyzed, and the transfer function of the model is obtained by the experimental modeling method. The experimental results show that the cascade control of the inner loop can effectively overcome the influence of the two disturbance, and can increase the gain of the main controller, so as to effectively control the two stage of the control difficulty.[Keywords]control simulation cascade control目录第 1 章 绪论..............................................................................................................11.1 系统总体设计............................................
