Abstract This paper proposes a set of strategies to control the superheat (SH) value of an Organic Rankine Cycle (ORC). This ORC corresponds to an experimental test bench aimed at developing a waste heat recovery system to be connected to the cooling circuit of a light-duty vehicle. Three strategies have been developed and tested experimentally. The first one is a linear control based on a PI controller valid for a given operating point. The second, valid for the same operating point, proposes an LPV (Linear Parameter-Varying) approach, less conservative and more accurate than the first one. Finally, a third strategy also using the LPV framework provides a controller valid in the full operating range of the test bench.

用于回收发动机冷却系统废热的有机朗肯循环的过热控制

摘要 本文提出了一套控制有机朗肯循环 (ORC) 过热度 (SH) 值的策略。该 ORC 对应于一个实验测试台，旨在开发连接到轻型车辆冷却回路的废热回收系统。已经开发出三种策略并进行了实验测试。第一个是基于对给定工作点有效的 PI 控制器的线性控制。第二个，对于相同的操作点有效，提出了 LPV（线性参数变化）方法，比第一个更不保守且更准确。最后，同样使用 LPV 框架的第三种策略提供了在测试台的整个操作范围内有效的控制器。
