论文摘要
在本文中,我们将最佳的LQ控制器应用于灌溉网络,该结构具有固有的结构,该结构允许分布式实现。该网络由水库和连接的水运运河组成。目的是在农民取水时保持水平接近设定点。 LQ控制器是使用运河动力学的一阶近似设计的,而用于评估的仿真模型则使用三阶管动力学。将性能与使用三阶管动力学设计的P控制器和LQ控制器进行比较。结构化控制器的表现优于P控制器,并且接近第三阶LQ控制器对干扰排斥的理论最佳。
In this paper, we apply an optimal LQ controller, which has an inherent structure that allows for a distributed implementation, to an irrigation network. The network consists of a water reservoir and connected water canals. The goal is to keep the levels close to the set-points when farmers take out water. The LQ controller is designed using a first-order approximation of the canal dynamics, while the simulation model used for evaluation uses third-order canal dynamics. The performance is compared to a P controller and an LQ controller designed using the third-order canal dynamics. The structured controller outperforms the P controller and is close to the theoretical optimum given by the third-order LQ controller for disturbance rejection.
