在工业过程控制中,许多对象都具有自衡特性,这类对象的动态特性常用传递函数 G_0(s)=K_0/(T_0S+1) e~(-τs)(1)来近似。Shinsky认为,任何复杂的多容对象都可等价为一阶纯滞后对象。使用这种近似模型不仅给系统的分析、设计带来方便,而且还拥有大量的资料(包括实验数据、图表、曲线以及调节器参数整定公式等)。因此,式(1)作为典型工业对象之一在过程控制中获
In industrial process control, many objects have self-balancing characteristics. The dynamic properties of such objects are approximated by the transfer function G_0 (s) = K_0 / (T_0S + 1) e ~ (-τs) (1). Shinsky argues that any complex, multi-volume object can be equivalent to a first-order, purely lagged object. The use of this approximate model not only brings convenience to the analysis and design of the system, but also has a lot of data (including experimental data, graphs, curves and regulator parameter tuning formula). Therefore, equation (1) is one of the typical industrial objects in process control
