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λ_ij来衡量。相对增益λ_ij的定义是在其他控制系统均为开环时，第j个控制变量U_j对第i个输出变量Y_i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λ_ij=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，λ_ij偏离l就越远。因此，相对增益λ_ij可用来衡量控制系统间关联的程度。
