What is Energy Efficiency in Control Systems?
Energy Efficiency in Control Systems optimizes control algorithms to minimize power consumption in networked and battery-operated systems using predictive control, clustering, and performance trade-offs.
This subtopic addresses energy minimization in control systems for applications like IoT, HVAC, and cyber-physical systems (CPS). Key techniques include fuzzy cognitive maps for HVAC energy reduction (Behrooz et al., 2018, 187 citations) and hybrid physics-guided machine learning for CPS control (Rai and Sahu, 2020, 270 citations). Over 1,000 papers explore trade-offs between energy use and control performance in automation.
Why It Matters
Energy-efficient controls cut operational costs by 20-40% in industrial HVAC systems (Behrooz et al., 2018) and extend battery life in IoT networks. In CPS, hybrid physics-ML methods reduce energy in control loops while maintaining stability (Rai and Sahu, 2020). Fault-tolerant controls ensure reliability in energy-constrained environments like networked systems (Abbaspour et al., 2020). These advances lower environmental impact in large-scale automation deployments.
Key Research Challenges
Nonlinearity in Energy Models
Control systems face nonlinear dynamics that complicate energy optimization, as seen in HVAC applications. Fuzzy cognitive maps address this but struggle with real-time adaptation (Behrooz et al., 2018). Balancing accuracy and computation remains difficult (Rai and Sahu, 2020).
Fault Tolerance vs Efficiency
Active fault-tolerant controls maintain performance but increase energy use in faulty states. Designing resilient systems without excessive power draw is challenging (Abbaspour et al., 2020). Network delays in NCS exacerbate trade-offs (Aubrun et al., 2008).
Scalability in Networked Systems
Energy efficiency degrades in large-scale CPS and IoT due to communication overhead. Hybrid modeling helps but requires massive computation (Rai and Sahu, 2020). Data processing for monitoring adds further load (Zhong et al., 2014).
