The expectation is to get both motor armature currents to match, indicating successful load sharing. The new idea of using Model Reference Adaptive Systems (MRAS) approach has been applied to design a control system such that two motors are identical in speed-torque characteristics. The design can be achieved in such a way that the two motors can contribute the same amount to the total load in the case that the DC motors are identical, or contribute partly to the total load and proportionally to their nominal torques in the case that the two motors are not identical. Both simulation and experimental results confirm the precise and robust performance and the ease of tuning and implementation, featured by the proposed control structure. The slave motor current strictly follows the master motor current with a maximum error between them is always smaller than 5%.","PeriodicalId":347974,"journal":{"name":"2013 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114750606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel synchronization method for redundant multivariable controllers applying the incremental dissipativity and the asymptotically positive-realness incremental-constraint (APRiC) is presented in this paper. As an alternative to the control summation in classical reliable control systems, only one scalar variable, which is the calculated supply rate, is exchanged among the member controllers. A dissipation-based quadratic constraint with respect to the control and output increments is developed from the APRiC for the redundant controllers in this approach. The APRiC is transformed into a quadratic constraint on the control vector, which is then imposed on the MPC optimization as a stability constraint. When a failure is detected, the stability constraint of the standby controller will be activated from the lower bound of the supply rate being transferred from the duty controller. The system is stabilized and dependable by the operations of such decentralized duty and standby architecture.","PeriodicalId":347974,"journal":{"name":"2013 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"434 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126098633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the highly nonlinear and time-varying nature of the EDM process, conventional gap width control methods do not perform efficiently, and their parameters need frequent tuning to achieve stable and efficient machining. The proposed gap control method uses an intelligent type-2 fuzzy logic inference system to control the gap distance between the electrode and the workpiece. The main advantage of this proposed method is its robustness to variations in machining conditions. In addition to removing the need for constant parameter tuning, the proposed control system results in enhanced accuracy and stability in the control performance.","PeriodicalId":347974,"journal":{"name":"2013 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125283602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intermittent data dropouts may incur concurrently to all vehicle agents in this formulation. Demands on communication links and online data are limited with a perturbed state-feedback strategy, which consists of a static cooperative-state feedback and an online-optimizing perturbation. The former compensates for the interagent communication-coupled dynamics. The latter attends to constraints and data losses, adopting only decoupled objective functions. The state feedback gain is determined in accordance with the interconnection topology of the formation, which is described by a directed graph in this paper. The ADC - asymptotically dissipative constraint, is employed in the overriding control strategy of stabilizing agents such that the inter-operability between remote manoeuvres and local autonomous commands becomes practically realizable. The equilibrium-independent supply rate and storage function are used in the stabilizability condition in this development for the final-state tracking of the cooperative formation problem.","PeriodicalId":347974,"journal":{"name":"2013 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127981506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the microscope head may drift by small amounts, which reduces the precision of the localization method. This paper proposes solutions to these problems based on the PHD Filter. To begin, a method for extracting protein positions from microscopy images is proposed. Tracking is provided on the extracted data using the PHD Filter framework for multiple object tracking, and a specially adapted particle filter for bias estimation is developed which exploits the PHD filter to estimate the likeliest position of the microscope.

It is however difficult to use conventional air/fuel control solutions for a lean-burn engine as the fuel duration is controlled to achieve desired torque, while airflow is controlled by the throttle valve to maintain air/fuel ratio demand. So for lean-burn motorcycle engine, the throttle valve must be automatically controlled depending on airflow requirement. However airflow cannot be controlled directly by throttle position due to high error. Since the airflow is closely related to the manifold pressure, this paper proposes an adaptive controller for pressure intake manifold control of a motorcycle engine using an electronic throttle valve control. The throttle position is employed as the control input for maintaining desired intake manifold pressure, and is designed based on a lead-lag compensator. The speed-density solution is employed to estimate the parameter of dynamic model. The root-locus technique is used to design the adaptive controller. Performance of the proposed controller is evaluated using a nonlinear motorcycle engine model in matlab/Simulink and experimental validation.","PeriodicalId":347974,"journal":{"name":"2013 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128200575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The weakness of these s is to cause energy loss during acceleration, whereas Torque Vectoring System could improve the driving stability without deceleration during cornering or acceleration. An additionally corrective torque based on desired yaw moment is computed from reference yaw rate and sideslip angle and then applied to the left and the right rear wheels.
