We apply the method to drone trajectory optimization in environments modeled by Gaussian Mixture Models (GMMs), specifically focusing on wildfire monitoring in northern Mexico.

The tuning of the predictor is proposed for two disturbance rejection scenarios, the first focusing on the prediction error performance and the second on closed-loop robustness.

The estimation of frequency response points from data obtained in such experiments is typically based on describing function theory, which assumes purely sinusoidal closed-loop responses and neglects higher-order harmonics. However, this assumption is often violated in low-order systems with poor filtering characteristics, resulting in reduced estimation accuracy. To address this issue, several alternatives, such as the saturation relay and pre-load relay, have been proposed in the literature, offering improved estimation performance. In this work, it is introduced a gain-changing nonlinear scheme for frequency points identification that enhances the accuracy of existing approaches. The experiments follow a similar structure to standard relay feedback tests, thus preserving their well-known advantages while significantly reducing estimation errors. Furthermore, by incorporating calculated time delays and dynamically adjusting the gain-changing parameters, the method generates multiple closed-loop oscillation conditions to identify several frequency response points, all while keeping the output amplitude within safe operational limits. Simulation results demonstrate a substantial improvement in estimation accuracy compared to both traditional and enhanced relay-based methods, offering a precise and practical solution for frequency response identification in industrial process control.</div></div>","PeriodicalId":50489,"journal":{"name":"European Journal of Control","volume":"87 ","pages":"Article 101437"},"PeriodicalIF":2.6,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145791111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Timely detection and mitigation of such attacks are imperative for the safe operation of CPS. This paper proposes a novel residual generator design method for enhanced detection of bias injection attacks (BIAs) in linear CPS driven by white Gaussian noise. Specifically, we define a flexible attack impact metric based on the weighted norm of the injected bias and a detectability metric based on the Kullback-Leibler divergence. Using these two metrics, we characterize the worst-case BIAs as those that minimize detectability while maintaining a specified minimum impact. For residual generation filter synthesis, we formulate two optimization problems: one for maximizing the detectability of worst-case BIAs at the attack onset and the other at steady state. Since these two problems are inherently conflicting, we employ the ϵ-constraint method to obtain Pareto-optimal solutions that balance transient and steady-state detectability. The effectiveness of the proposed filter design method is demonstrated through numerical simulations, with a comparison against two state-of-the-art benchmarks: the Kalman filter and the <span><math><mrow><msub><mi>H</mi><mo>−</mo></msub><mo>/</mo><msub><mi>H</mi><mn>2</mn></msub></mrow></math></span> filter.</div></div>","PeriodicalId":50489,"journal":{"name":"European Journal of Control","volume":"87 ","pages":"Article 101427"},"PeriodicalIF":2.6,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145738135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Convergence properties are established alongside design selections that ensure the passivity condition is fulfilled. By minimising the reliance on identification tests, this methodology is substantially faster than existing model-free ILC algorithms. It is tested on a key stroke rehabilitation problem using functional electrical stimulation (FES) for hand/wrist tracking. Experimental results using the new ILC approach with eight participants show that three hand/wrist references can be tracked using an average of 56% fewer experimental inputs compared with the most accurate previous approach.
