内容预览：描述：如果除了主过程变量外，还测量更多的系统变量并作为辅助过程变量进行反馈，并创建下级控制环，则可建立级联控制结构。从而就有一个主站 (或主) 控制环和一个从站 (或辅助) 控制环。级联控制是过程设备中最常见的一种控制系统结构。本项目实例说明了级联控制的应用，它控制带有一个主过程变量和一个辅助过程变量的仿真过程。该应用注意事项的目标是，说明级联控制环组态中的问题，尤其是在实际应用的各种工作模式下与获得快速动态行为和正确行为有关的问题。 ......

The project example shows the application of cascade control to a simulated process with one main and one auxiliary process variable.

Objective of the Application
A cascade control structure can be established if, beside the main process variable, more system variables are measured and fed back as auxiliary process variables, creating subordinate control loops. Thus there is a master (or main) control loop and a slave (or auxiliary) control loop.
Cascade control is one of the most common control system structures in process plants.

The objective of this application note is to show the issues in configuration of cascade control loops that are particularly relevant to achieve fast dynamics and correct behaviour in all operating modes of real world applications.

Main contents
The following issues are discussed in this application note:

Interaction between master and slave controller with respect to controller tuning
Interaction between master and slave controller with respect to operating mode changeovers
Simulation example
