A model-based approach has been used which predicts experimentally observed engine performance for biodiesel. The basic idea is to develop inverse optimal control and utilize Lyapunov function in order to achieve good performance. The obtained controller gain guarantees the global convergence of the system and regulates the flows for the Variable Geometry Turbocharger and Exhaust Gas Recirculation systems in order to minimize the NOx emission and smoke of biodiesel engine. Simulation of the control performance shows the effectiveness of this approach.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"212 0 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134017078","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 method uses a rewriting of the observation error to avoid the constraint (due to the interconnection terms) that generally arises in observer design for these systems. The approach that we use to express the observation error permits to use results on stabilization of large scale delay discrete-time systems to solve the problem. The proposed observers are free of the interconnection terms and the observation error are unbiased. Each observer gain is parameterized via a single gain matrix which is computed via LMI. A tractable algorithm permits to compute the proposed observer easily.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126240100","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}

In practical situations, the reconstruction of the original system is strongly influenced by the choice of the variable transmitted over the communication channel. This paper aims to analyze this influence in the context of mathematical singularities occurring in the evolution of the chaotic manifolds used in encryption. We analyze two systems having a chaotic behavior, a discrete system, the Hitzl-Zele map, and a continuous one, the Colpitts oscillator. We show the existence of observability singularities in both cases. The numerical experiments point out that the dynamics of the discrete system falls in these singularities sets, but very infrequently. More surprisingly, the dynamics of the continuous system can not pass through the singularity, which is situated at infinity. But an exponential factor allows the chaotic dynamics to approach the vicinity of the singularity better than 10-7 and that, for about 30% of its duration. The noise inherent in analog signals are much higher than this value, the observation of the system is impossible in practice.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124935514","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 solution we bring to this problem is firstly to analyze the observability of systems under random sampling and secondly to synthesize an impulsive observer. Here, the first approach is based on the concept of compressive sampling which is well-known in signal processing theory. A synthesis of impulsive observers will be presented for some special cases. These observers allows to detect the active mode and rebuild the state under sparse measurement.

While the former adds an incremental steer angle to the driver's input, the latter imposes a torque by means of the rear axle. The active front steer control is actuated through the front tires, while the rear torque vectoring can be actuated through the rear tires. A nonlinear controller using the super-twisting algorithm is designed in order to track in finite time lateral and yaw angular velocity references. We consider one estimation method, given in the literature, to estimate the tire-road coefficient, and we design a dynamic controller to estimate the perturbing terms due to the vehicle's mass and inertia variations, and due to the variation of the tire parameters. Comparisons with a simple PI-based controller are done, and some simulation results highlight the advantages of the proposed controller.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132625671","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}

This method is based on a heuristic Kalman algorithm (HKA) and is described as more speedy and more accurate optimization methods. First, we introduce the general form of the H∞ control law obtained by solving a partial differential equation labeled Hamilton-Jacobi-Isaacs equation. An analytic solution to this equation is described for the Euler-Lagrange Systems. Second, based on this solution and on the PID control law resulting, it is shown how to use the optimization method to adjust optimally the controller's gains ensuring a minimum L2 - gain and thus disturbance attenuation. Third, we apply this optimization algorithm in the trajectory tracking and disturbance attenuation problem of a three degree of freedom robot manipulator. The simulation results show the effectiveness of the H∞-PID control law optimized by the HKA method.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123077451","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}

It provides a system of variable voltage and frequency from fixed input grid voltage. Therefore, the output of the matric converter is directly affected by unbalanced input grid voltage. Some research works have been made to overcome this problem by using Proportional integral (PI) control. However, PI control has limited performance when it is used in nonlinear systems. Fuzzy logic controller (FLC) has the advantage to control highly nonlinear and difficult to model systems. Therefore, the combination of these two controllers to form a fuzzy supervisory control (FSC) can give better performance to overcome the limitation of PI control in nonlinear systems. In this paper a novel FSC based control method is proposed. The FSC performs closed loop control of the output current to improve the performance of the MC powered by unbalanced grid voltage. The working principle, Venturini modulation strategy of MC and characteristics of FSC are presented. The performance of FSC is tested and compared for balanced and unbalanced grid.","PeriodicalId":199135,"journal":{"name":"3rd International Conference on Systems and Control","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124900740","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}
