混杂系统包含有离散子系统和连续子系统,系统中变量转换复杂,参数存在不确定性,导致故障诊断的误报率较高。针对此问题,以单相全桥逆变器为研究对象,提出运用线性分式变换的键合图(Bond Graph in Linear Fractional Transformation,BG-LFT),建立系统参数不确定性混合诊断键合图(Diagnostic Hybrid Bond Graph,DHBG)模型,并根据模型产生自适应阈值。基于混杂键合图的因果关系和结构特性,从DHBG中导出所有有效模式下的鲁棒解析冗余关
本文实例讲述了PHP带节点操作的无限分类实现方法。分享给大家供大家参考,具体如下:
包含(移动多个节点;移动单个节点;删除多个节点;删除单个节点;新增节点),另附数据库表结构
一、db sql语句
//db used for php无限分类
create table tree(
id int(10) not null primary key auto_increment,
name varchar(255) not null,
lft int(10) not null defaul
本文实例讲述了php通过前序遍历树实现无需递归的无限极分类。分享给大家供大家参考。具体如下:
大家通常都是使用递归实现无限极分类都知道递归效率很低,下面介绍一种改进的前序遍历树算法,不适用递归实现无限极分类,在大数据量实现树状层级结构的时候效率更高。
sql代码如下:
CREATE TABLE IF NOT EXISTS `category` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`title` varchar(50) NOT NULL,
`lf
