A Linear Time Invariant (LTI) energy-maximising control strategy for Wave Energy Converters (WECs) is proposed in this paper. Using the fundamental requirement of impedance-matching, the controller is tuned to maximise the energy obtained under polychromatic wave excitation. Given the LTI nature of the proposed controller, the design and implementation procedure is significantly simpler than well-established energy-maximising controllers, including state-of-the-art numerical optimisation routines, which are predominant in this field. Additionally, a LTI constraint handling mechanism is provided. The effectiveness of both the LTI control strategy and the constraint handling mechanism are assessed using regular and irregular waves in unconstrained and constrained cases. The resulting performance is compared to those obtained using existing WEC optimal control strategies. Finally, the benefits, in terms of power production, for both the controller and the constraint handling mechanism are explicitly highlighted by means of an application case.

用于波浪能设备的能量最大化的线性时不变控制器（LiTe-Con）

本文提出了一种波能转换器（WEC）的线性时不变（LTI）能量最大化控制策略。使用阻抗匹配的基本要求，对控制器进行了调整，以使在多色波激励下获得的能量最大化。鉴于所提出的控制器的LTI性质，其设计和实现过程比公认的能量最大化控制器（包括在该领域占主导地位的最新数字优化例程）要简单得多。此外，提供了LTI约束处理机制。在无约束和受约束的情况下，使用规则波和不规则波来评估LTI控制策略和约束处理机制的有效性。将所得性能与使用现有WEC最佳控制策略获得的性能进行比较。最后，通过一个应用案例明确强调了控制器和约束处理机制在发电方面的优势。
