Abstract Split range control is used to extend the steady-state operating range for a single output (controlled variable) by using multiple inputs (manipulated variables). The standard implementation of split range control uses a single controller with a split range block, but this approach has limitations when it comes to tuning. In this paper, we introduce a generalized split range control structure that overcomes these limitations by using multiple independent controllers with the same setpoint. Undesired switching between the controllers is avoided by using a baton strategy where only one controller is active at a time. As an alternative solution we consider model predictive control (MPC), but it requires a detailed dynamic model and does not allow for using only one input at a time.

用于扩展操作范围的多输入单输出控制：使用指挥棒策略的广义分割范围控制

摘要 分程控制用于通过使用多个输入（操纵变量）来扩展单个输出（受控变量）的稳态工作范围。分程控制的标准实现使用带有分程块的单个控制器，但这种方法在调整方面存在局限性。在本文中，我们介绍了一种通用的分程控制结构，该结构通过使用具有相同设定点的多个独立控制器来克服这些限制。通过使用一次只有一个控制器处于活动状态的接力棒策略，可以避免控制器之间不希望的切换。作为替代解决方案，我们考虑模型预测控制 (MPC)，但它需要一个详细的动态模型，并且不允许一次只使用一个输入。
