In this paper, a hybrid vector and sector model predictive control (HVS-MPC) strategy is proposed for medium and small power converter systems with high control frequency to improve system performance on three aspects. First, a sector optimization algorithm is adopted to reduce computational burden according to radiation range of basic vector and sector location of target vector. Second, a vector synthesis algorithm is adopted in linear modulation area to improve vector control accuracy with fixed switching frequency by vector operation time calculation and sequence setting. Third, in order to improve system performance in over modulation area without extra computational burden, the hybrid vector modulation algorithm is proposed based on target vector length and modulation area. Finally, the proposed strategy is verified through experiment and simulation.","PeriodicalId":54965,"journal":{"name":"International Journal of Control Automation and Systems","volume":"46 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940532","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}

The scheme comprises a PID force feedback controller and a position/velocity feedback controller. Its objective is to apply the desired amount of pressure while ensuring closed-loop stability. The PID force feedback controller operates in contact mode, while the position/velocity feedback controller operates in non-contact mode. For the PID control, a non-quadratic Lyapunov function is devised together with an invariant domain of attraction within the contact region, including the equilibrium steady state. For the non-contact region where the state trajectories stay only temporarily, the position/velocity feedback control is equipped with a disturbance compensation term on the basis of a Lyapunov min-max approach, which leads to a quadratic Lyapunov function. Notice the two different ways of achieving infinite gain operation for handling modeling errors and disturbances: infinite gain at DC, resulting from integral action in the contact mode, and infinite gain at equilibrium, resulting from the use of a signum function in the non-contact mode. The asymptotic stability of the overall switching control system is proven by demonstrating that the two Lyapunov functions defined in the contact and non-contact regions satisfy certain decreasing properties. Simulations confirm that the applied force closely tracks the desired value in the presence of a DC disturbance and model uncertainty.","PeriodicalId":54965,"journal":{"name":"International Journal of Control Automation and Systems","volume":"41 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940534","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}

The voltage adjustment performance of the Boost converter is governed by a feedback PID controller system. The realism of the proposed power system is validated through using the Simscape environment, which is adopted to model and simulate the PID based Boost converter system. The presented Simscape system is more applicable in real-time than the Simulink model as the model of the Simscape components and devices is built based on practical considerations like tolerance and parasitic elements. PSO optimization algorithm is utilized to develop the performance of the PID controller through operating the converter system based on best values for PID gain parameters. The simulation design of the proposed power system is implemented in the Matlab tool and its results are presented and discussed to evaluate the performance of the presented feedback PID controller. To validate the robustness of the converter performance the voltage adjustment behavior of the PID controller is assessed based on disturbance of supply voltage, reference voltage and resistive load working conditions. Simulation results revealed the ability of the PID controller to reject the supply voltage disturbances and enable the Boost output to track the demand input trajectories effectively.","PeriodicalId":54965,"journal":{"name":"International Journal of Control Automation and Systems","volume":"76 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940461","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}

The communication topology is formed by the strongly connected time-varying directed graphs with the column stochastic weight matrices, where each node updates its own decisions by exchanging information with neighbouring nodes. It is not feasible to sample objective function values at several consecutive points simultaneously since the online setting is time-varying. To solve this problem over directed graphs, a push-sum one-point bandit distributed dual averaging (PS-OBDDA) algorithm is proposed, where the one-point gradient estimator is employed to estimate the true gradient information, to guide the updating of the decision variables. Moreover, by selecting the appropriate exploration parameter δ and step sizes α(t), the algorithm is shown to achieve the sublinear regret bound with the convergence rate (O({T^{{5 over 6}}})). Furthermore, the effect of one-point estimation parameters on the regret of the algorithm in online settings is explored. Finally, the performance of the algorithm is evaluated through simulation.","PeriodicalId":54965,"journal":{"name":"International Journal of Control Automation and Systems","volume":"25 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940732","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}

The control objectives are to achieve formation acquisition (i.e., vehicles form a predefined geometric shape) and formation maneuvering (vehicles move as a whole following predefined velocity). For the first objective, the nonlinear model is transformed into a dynamic model similar as the Euler-Lagrangian system with uncertain parameters. Then, we propose a rigid graph based adaptive dynamic formation control law, which enables the robotic vehicle system to converge to the target formation. Meanwhile, collision avoidance between vehicles can be achieved because the rigid graph theory naturally ensures the distance constraint. Then, formation maneuvering problem is investigated, on the basis of formation acquisition, a predefined velocity signal is added to the proposed adaptive formation control law such that robotic vehicles move as a whole following the predefined velocity. Compared with the existing results, the proposed rigid graph based formation control method can effectively reduce the appearance of non-desired equilibrium points of traditional distance based methods, moreover, the distance between robot vehicles can be time-varying, and the formation shape or size can be time-varying. Simulation results confirm the effectiveness of the dynamic formation control law.","PeriodicalId":54965,"journal":{"name":"International Journal of Control Automation and Systems","volume":"20 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940558","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}
