补充资料:布里斯托尔相对增益
分子式:
CAS号:

性质:在一个装置上设置多个控制系统时,系统间会存在相互耦合。但其关联程度可用布里斯托尔相对增益λij来衡量。相对增益λij的定义是在其他控制系统均为开环时,第j个控制变量Uj对第i个输出变量Yi通道的放大系数(增益)与该通道在其他控制系统均为闭环时放大系数(增益)之比,称为相对增益。由于是布里斯托尔提出的,所以又称布里斯托尔相对增益。当系统间无耦合时,一个控制回路是处于开环或闭环状态,对另一个控制回路是不会起影响的,故λij=1。但在系统间存在耦合时,情况就不同了,耦合越严重,一个控制回路处于开环或闭环,对其他控制回路影响就越大,λij偏离l就越远。因此,相对增益λij可用来衡量控制系统间关联的程度。
