This paper highlights the differences between a simple sensorless method and an adaptive flux and speed observer for a five-phase induction motor control. The drive is controlled using space vector modulation direct torque control (DTC- SVM) approach. The power measurement used for speed computation is simple, with a minimum processor time and memory, and relatively robust against parameters variation when compared with the adaptive observer based approach. Simulation verification and real time implementation are presented in the paper.

Quadratic stability / stabilization / estimation for Takagi-Sugeno models have now reached maturity. Lots of results concerning performances (H 2 , H ∞ , D-stability) for TS models with uncertainties, noise, time-delays ... exist in the literature. Nevertheless, it is illusive thinking to solve every nonlinear problem of stability using a simple quadratic Lyapunov function. Moreover, most of the nonlinear systems only have properties of local stability. This work follows the idea of using non quadratic Lyapunov functions for continuous Takagi-Sugeno models restricting the global asymptotic stability to a local one. Therefore, it tries to estimate the best stabilization domain possible. A rather "simple" LMI constraints problem is derived to answer to this question.

The single-phase induction machine has the advantage of being powered by a single-phase voltage source. The availability of this power allows it to be widely used: electric household appliances, portable machine tools... However, this type of machine has not yet taken its whole share from various works present until now, in comparison with the three-phase asynchronous machine. We propose by the means of this article, an approach combining the performances of the commands which are based on the tools of the artificial intelligence (neural networks and fuzzy logic) in the form of a hybrid control (neural-fuzzy - fuzzy) applied to control the single-phase induction motor supplied by PWM inverter. The simulation results show the feasibility and good performance obtained by the proposed control. Namely, improved response time and robustness of the system overlooked the disruption caused by the application of a load torque or speed rungs on the dynamics of the global system. That reinforces the principle of vector control with a good decoupling between the electromagnetic torque and rotor flux. © 2011 IEEE.

In this paper, we present a model to elaborate the sources of randomness in multiple tiling array data. We also propose a new probe score system which integrate the intensity information of a probe and its neighbors. This new score system is obtained by using slide window and median polish strategies. These strategies firstly unify probe affect across probes and the array effect across arrays based on the region-specific fixed values interpreting the transcription levels of regions in probes, then unite these unified information into the region-specific fixed values. And this united information become a new standard to evaluate that probes are or aren't in transcriptional regions. Similar to median method, our method is a way that integrate the information from multiple arrays in the analysis stage rather than the results stage. A classical hidden Markov model (HMM) is used to model the distribution of tilling array probe scores in transcribed and non-transcribed regions and then to predict the transcribed fragments. The priority of the proposed score system is illustrated based on Affymetrix's RNA tiling array data.

In this paper, the distributed robust output regulation problem of linear multi-agent systems (MAS) is considered. The driving force from the active leaders or the environmental disturbances is formulated as an input of an exogenous system (or exosystem) of the considered multi-agent networks. A systematic distributed design approach is proposed to handle output regulation via dynamic output feedback with the help of canonical internal model (IM). With common solutions of regulator equations and Lyapunov functions, the distributed robust output regulation with switching interconnection topology is designed to achieve collective aims.

The single-phase induction machine (SPIM) has the advantage of being powered by a single-phase voltage source. The availability of this power allows it to be widely used: electric household appliances, portable machine tools... However, this type of machine has not yet taken its whole share from various works present until now, in comparison with the three-phase induction machine. With the object of contributing to the study of this machine, we propose in this article a new decoupling approach in the vector control block, based on the the Fuzzy Logic; in order to solve the problem of decreasing the rotor flux. Indeed, the vector control of single phase induction machine using conventional decoupling approaches has a remarkable decrease of rotor flux when the machine is powered by a real voltage source inverter (VSI). For three different decoupling approaches with two types of supply: perfect voltage source and real voltage source inverter; a comparative study through numerical simulations is presented. The simulation results show the feasibility and good performance obtained by the proposed approach.

In this paper, the problem of designing of robust state-feedback H ∞ controller for uncertain sampled-data control systems with output constraints have been investigated base on jump system model of sampled-data system using constant Lyapunov function (CLF) approach. The online algorithm of the H ∞ receding horizon optimization design for the norm-bounded parametric uncertain system is proposed. The optimal state-feedback H ∞ controllers are obtained and these controller can provide a performance tradeoff with respect to output constraints, i.e., the control strategy offers the capability of relaxing the performance level automatically in order to obey output constraints in the case of a larger disturbance. When the disturbance is restored to a usual situation, this control strategy can also improve the performance of system automatically.

This paper aims to address the robust convergence problem that arises from discrete-time iterative learning control (ILC) systems subject to random disturbances. Two alternative approaches are considered in order to achieve the perfect output tracking of the stochastic discrete-time ILC systems in the sense of both expectation and variance, which use the tracking error and the input error for analysis, respectively. It is shown that the convergence results of two approaches to ILC can be established by developing some statistical expressions in super-vector forms. Moreover, it is demonstrated that the convergence results of two approaches to ILC are not always equal, and they can keep the same only in the case where the controlled plants are square.
