A new design approach based on the minimal order nonlinear observer is presented to detect and locate leaks in complicated pipelines, since the measurements of pressure and flow are realizable only at the two extremes of the ducts, the state decoupling technology is utilized in generating the residual values and an appropriate method of linear coordinate transformation is selected.
提出基于最小阶非线性观测器的设计方法,通过对管路两端点处的压力流量在线采集处理,运用状态解耦技术,选择适当的状态线性变换方式,有效地分离出反映管路中间节点状态的残差数值,进而对非线性状态方程序列生成相应的系统残差集,以达到对管内泄漏的有效定位。
