实时和模型预测控制有望使城市排水系统(UDS)自适应,协调,和动态最优。虽然早期的实现是有希望的,现有的控制算法在计算费用方面存在缺陷,信任,系统级协调,和劳动力成本。线性反馈控制在计算费用方面具有明显的优势,解释,和协调。然而,当前构建线性反馈控制器的方法需要校准的软件模型。在这里,我们提出了一种自动方法,用于生成仅需要系统响应数据的可调线性反馈控制器。控制器设计包括三个主要步骤:(1)使用因果推断工具估计网络连接,(2)辨识线性,近似网络的时不变(LTI)动力系统,(3)设计并整定基于LTI城市排水系统逼近的反馈控制器。洪水安全,防侵蚀,在分离的下水道模型上,在190个设计风暴中评估了该方法的水处理性能。强有力的结果表明,生成有效的系统知识所需的系统知识,安全,和UDS的可调控制器是令人惊讶的基本。此方法允许仅根据传感器数据或基于过程的模型进行控制器的近交钥匙综合。
Real-time and model-predictive control promises to make urban drainage systems (UDS) adaptive, coordinated, and dynamically optimal. Though early implementations are promising, existing control algorithms have drawbacks in computational expense, trust, system-level coordination, and labor cost. Linear feedback control has distinct advantages in computational expense, interpretation, and coordination. However, current methods for building linear feedback controllers require calibrated software models. Here we present an automated method for generating tunable linear feedback controllers that require only system response data. The controller design consists of three main steps: (1) estimating the network connectivity using tools for causal inference, (2) identifying a linear, time-invariant (LTI) dynamical system which approximates the network, and (3) designing and tuning a feedback controller based on the LTI urban drainage system approximation. The flooding safety, erosion prevention, and water treatment performance of the method are evaluated across 190 design storms on a separated sewer model. Strong results suggest that the system knowledge required for generating effective, safe, and tunable controllers for UDS is surprisingly basic. This method allows near-turnkey synthesis of controllers solely from sensor data or reduction of process-based models.
