Specifically, automatic control can play a pivotal role in improving irrigation scheduling. In this context, incorporating real-time soil moisture (SM) forecasting in irrigation can potentially improve the efficiency of crop water management. However, the complexity of the analytical models that describe soil-water dynamics limits the development of practical and accurate solutions that include SM forecasting in decision-making. Currently, irrigation decisions are based on present and past SM data. This approach can be enhanced if, in addition to those, future or SM forecasting is incorporated. We formulated an SM model-based moving horizon estimation (MHE) and prediction strategy. For this, we propose a parametrizable blue SM control-oriented prediction model (SMCOPM) that obeys a soil-water balance. The SMCOPM is periodically parametrized using a proposed MHE approach, which provides adaptability, guarantees optimality, prevents overfitting, and ensures the water balance fulfillment and stability of the SMCOPM. The SM forecasting is performed by solving the parametrized SMCOPM as a function of rain, irrigation, and temperature forecasts. We evaluated the MHE and prediction strategy using, as a case study, observed data from a commercial sweetcorn field using subsurface irrigation in South Florida. The results show that by using this strategy, the SM can be predicted three days in advance with an average SM prediction error and a dispersion that significantly improves as the SMCOPM adapts over time, demonstrating convergence toward an error less than 2% and dispersion less than 3%. Consequently, the results corroborate the SMCOPM suitability, the proposed estimation strategy’s quality, and the SM behavior’s predictability. The proposed strategy has the potential for use in formulating predictive control approaches toward automating the irrigation process or scheduling irrigation actions.","PeriodicalId":13103,"journal":{"name":"IEEE Transactions on Control Systems Technology","volume":"33 1","pages":"106-118"},"PeriodicalIF":4.9,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our proposed approach seeks to minimize the conditional value-at-risk (CVaR) of the dispersion, thereby shifting the probability distribution away from the tails. This approach provides an optimization framework that is not overly conservative and can accurately capture more information about true distribution, compared with methods which consider only the expected value, or robust optimization methods. The main contribution of this brief is to present an approach that: 1) establishes an optimization problem with CVaR dispersion cost 2) approximated with one of the two novel surrogates which is then 3) solved using an efficient SCP algorithm. In 2), two approximation methods, a sampling approximation (SA) and a symmetric polytopic approximation (SPA), are introduced for transforming the stochastic objective function into a deterministic form. The accuracy of the SA increases with sample size at the cost of problem size and computation time. To overcome this, we introduce the SPA, which avoids sampling by using an alternative approximation and thus offers significant computational benefits. Monte Carlo simulations indicate that our proposed approaches minimize the CVaR of the dispersion successfully.","PeriodicalId":13103,"journal":{"name":"IEEE Transactions on Control Systems Technology","volume":"32 6","pages":"2468-2475"},"PeriodicalIF":4.9,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, simultaneously varying controls and turbine shape by considering the interactions between the control space and the turbine shape can significantly enhance the system performance in contrast to the conventional sequential design approach. This article delves into this prospect by introducing a control co-design (CCD) framework tailored for this simultaneous optimization for a variable-speed HKT rotor. The proposed CCD framework integrates a dynamic-hydrodynamic model that captures the intricate interplay between hydrodynamic performance and control strategies for the HKT under time-varying flow profiles. We systematically investigate cases with diverse control constraints in a time-varying flow environment to explore the coupling between the control space and the physical system. We demonstrate the advantages of the CCD framework over the conventional sequential design methodology through comparative study cases. CCD optimization considering a single flow condition leads to an overly specialized design that underperforms at other off-design conditions. The stochastic nature of the flow thereby highlights the need to account for a broader range of flow speeds in the HKT design process. To address this challenge, we introduce a multipoint CCD optimization that accounts for the annual flow probability distribution. The multipoint CCD approach demonstrates higher annual energy extraction compared to optimizations based on a single flow condition.","PeriodicalId":13103,"journal":{"name":"IEEE Transactions on Control Systems Technology","volume":"33 1","pages":"48-60"},"PeriodicalIF":4.9,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the application effectiveness of traditional RL is often limited by some insurmountable experimental conditions. Thus, developing new RL algorithms that can efficiently manipulate the quantum system dynamics is a crucial task. Prior research has shown that incorporating quantum mechanical properties into RL can improve learning performance. In this article, we consider the quantum control problem where only the target state can be accurately identified and introduce a quantum-inspired RL (QiRL) method. In particular, we propose a quantum-inspired exploration strategy to replace a commonly used \u0000<inline-formula> <tex-math>$epsilon $ </tex-math></inline-formula>\u0000-greedy strategy, as well as a quantum-inspired reward scheme to incentivize the learning agent. Numerical results on three quantum system control problems, i.e., one-qubit closed quantum system, two-level open quantum system, and many-qubit closed quantum system, verify the effectiveness of QiRL. Comparison results show that the proposed QiRL outperforms existing RL algorithms (deep Q-network and proximal policy optimization) in terms of stability and efficiency for solving quantum control problems.","PeriodicalId":13103,"journal":{"name":"IEEE Transactions on Control Systems Technology","volume":"33 1","pages":"61-76"},"PeriodicalIF":4.9,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
