中文说明：
双容水箱液位控制系统是一种采用先进的控制算法完成对液位的控制的系统, 它在食品加工、原油提炼、化工生产等诸多实用行业中都有广泛使用。本次设计中, 要求设计的超调量小，调节时间短和有自平衡能力等优点。首先要掌握生产工艺和控制流程的基本知识，选择合适的仪表。然后进行系统的设计，明确被控对象，并对系统中每个原件进行模型建立；根据系统要求选择合适的控制方法，对控制器进行参数整定。我们将充分利用计算机技术结合自动控制技术实现对水箱水位的精确控制。
English Description：
Double let water tank liquid level control system is a kind of advanced control algorithm of liquid level control system, it's in the food processing, oil refining, chemical production, and many other practical are widely used in industry.In this design, the design requirements of small amount of overshoot and adjustment time is short and has since the balance ability, etc.Must first master the basic knowledge of the production process and control process, select the appropriate instrument.Then the design of the system, controlled object, and the original system in each model;According to the requirements to choose the appropriate system control method, the controller parameter setting.We will make full use of computer technology in combination with the automatic control technology realize accurate control of water level in the tank.
