This paper investigates the design and validation of an improved robust control solution for the DOC-outlet temperature control by applying the error-based active disturbance rejection control (ADRC) method and the non-singular terminal sliding mode (TSM) scheme along with a second-order sliding mode approach. The second-order TSM scheme is introduced to substitute the proportional–derivative (PD) control in the conventional ADRC framework. A finite-time convergence of the sliding mode dynamics is consequently guaranteed and the tracking errors are driven to zeros asymptotically, which accordingly implies that a faster temperature response is expected. Moreover, the undesired chattering effect is eliminated, resulting in an inherently continuous control input signal. The extended state observer (ESO) is synthesized as a feedforward compensator to estimate and reject the total disturbance. Theoretical convergence and stability of the proposed control strategy are analyzed based on the Lyapunov approach. Selection of the controller parameters is further discussed as well. The effectiveness and robustness are finally examined through an extensive comparative study using simulation and experimental tests. Results demonstrate that the proposed continuous TSM control achieves superior temperature control performance, including faster disturbance suppression, more accurate set-point tracking, and greater robustness against internal model uncertainties and external disturbances compared to the conventional ADRC controller.</div></div>","PeriodicalId":50615,"journal":{"name":"Control Engineering Practice","volume":"159 ","pages":"Article 106316"},"PeriodicalIF":5.4,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629183","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}

The recent advancement of vehicle-to-everything (V2X) technology has provided abundant perceptual information for DRL agents, improving the accuracy and safety of decision control. However, existing research on green wave traffic scenes has difficulty adapting to multi-signal scenarios with single-signal countdown models, which lack complete signal state information. To address this limitation, an enhanced DRL model with bird’s eye view (BEV) design strategy is proposed for vehicle-road collaborative autonomous driving scenarios. The constructed model introduces a state prediction fusion strategy to compensate for state information. Specifically, state information is first predicted by fusing perception results from vehicles and roadside units (RSUs) at different moments. Then, the recommended velocity is derived for green wave passage, called the green wave velocity belt, and incorporate it into the state space as two variables in the state vector. Finally, a relevant reward term in the reward function is designed to guide agent learning strategies. The proposed method is trained on the basis of the parallel DreamerV3 framework.

By studying the internal and external disturbances affecting the aircraft during braking, these disturbances are classified based on their impact on the balance point of the wheel slip system. A method based on the induced ideal limit cycle is proposed to detect disturbances. An adaptive braking control strategy incorporating runway recognition technology was developed, enabling the braking system to adjust the target deceleration rate according to real-time disturbances.

The objective of this work is to experimentally assess the use of zone model-based predictive controllers (ZMPCs) for temperature control in an IH prototype used to heat a compressor in performance tests with constraints on unmeasured states. This choice was motivated by the importance of such tests in industry, the potential to shorten the transient duration using IH, and the existence of safety constraints on non-measurable temperatures. A test rig with an instrumented compressor was built to test the proposed framework with different controllers from the literature, including a reference-tracking model-based predictive controller (MPC) predictive controller (MPC) and a PI controller. A state-space model was identified using measured temperatures as states to describe the thermal dynamics of the compressor. Since the temperature required for ensuring safety constraints is not measurable in a regular compressor, a Kalman filter was used for state estimation. Experimental results show that all controllers satisfy the constraints and can track a reference step with zero steady-state error. The best result was achieved by ZMPC, where the heating time of the evaluated compressor was reduced from 70min to less than 10min while maintaining safe internal temperature conditions, which represents a reduction of approximately 90% in transient time.</div></div>","PeriodicalId":50615,"journal":{"name":"Control Engineering Practice","volume":"159 ","pages":"Article 106317"},"PeriodicalIF":5.4,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620644","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}
