波浪能转换器的能量最大化控制是一个非标准最优控制问题。虽然WEC的约束最优控制问题已经通过模型预测控制策略来解决，但是由于凸性问题，这种策略需要采用成本函数修改，并且算法计算复杂，使得实时实现困难。最近开发的家庭的直接转录方法提供了一个很有前途的替代方案，因为它们是计算效率和凸问题的结果。此外，对装置位移和速度以及动力输出力的约束很容易结合。可以使用单体和多体设备模型，以及单体或多体设备的阵列。
Energy maximizing control for wave energy converters (WECs) is a nonstandard optimal control problem. While the constrained optimal control problem for WECs has been addressed by model-predictive control strategies, such strategies need to employ cost function modifications due to convexity problems and the algorithms are computationally complex, making real-time implementation difficult. The recently developed family of direct transcription methods offer a promising alternative, since they are computationally efficient and a convex problem results. Moreover, constraints on both the device displacement and velocity, and power take off force, are easily incorporated. Both single-body and multibody device models can be used, as well as arrays of single-body or multibody devices.
