On the Method for Control of Tailgate Water Level of a Hydraulic Model

本文以重庆港河工模型试验中尾门水位控制问题为例,从现代控制理论角度探讨了河工模型微机控制系统中有关建立数学模型、动态参数估计和最小方差调节器的实现方法.经实际应用检验,这些方法理论基础坚实,跟踪控制可靠,精度较高,且实施步骤简单.

This paper presents a method of constructing the state-space equation, estimating it's parameters, and performing the minimum variance control over a physical model based upon the modern control theory and also gives an example of application to the control of tailgate water level in the model of a reach near the Chongqi Harbour of the Yangtze River. Results from the tracked values required and those actually obtained show close agreement. This method appears to be simple with high reliability.
