优先级
在每个控制周期,根据以下动力机制重建面板:
如果在YC_ReachableAct和UA_ ReachableAct向量中具有值+ N或-N,即至少具有1个CV或1个MV,则priority(优先级)是活动的。
在overview(概述)面板上,以下节点可按以下排序顺序显示在MV和CV行中。
树节点名称 | Priority Nr(优先级) | 描述 |
---|---|---|
Blending (混合) | 111 | 混合约束。 |
Ramping (斜坡) | 112 | 稳态和斜坡约束。 |
[Priority#] (优先级) | 1-100 | 常规MV/CV优先级。 |
[Optimisation] (优化) | 101 | 经济优化。 |
[Unconstrained] (无约束) | 0 | 未约束变量。 |

Priority
At each control period, the panel is rebuilt according to the following dynamic mechanism:
A priority level is active, if there is at least 1 CV or 1 MV with the value +N or -N in the YC_ReachableAct and UA_ ReachableAct vector.
On the overview panel the following nodes can appear in the MV and CV lines in the following sorting order.
Tree Node Name | Priority Nr | Description |
---|---|---|
Blending | 111 | Blending constraint |
Ramping | 112 | Stable and Ramp constraint |
[Priority#] | 1-100 | Regular MV/CV priorities |
[Optimisation] | 101 | Economic Optimization |
[Unconstrained] | 0 | Unconstrained variables |
