This paper deals with the problem of output feedback control of SISO nonlinear systems based on the multi-dimensional Taylor network (MTN) controller. It adopts the MTN controller as a network structure controller and the differential geometry as an analysis tool. It proves that, when the given conditions are met, the reference signal can be asymptotically tracked by the MTN controller. And also, it proves the MTN controller can realize the closed-loop system dynamic regulation. Finally, an example is given to prove the correctness of above.

This paper investigates the finite-time tracking control problem for rigid manipulator systems. The proposed controller is based on adding a power integrator technique, which guarantees global finite-time convergence of tracking errors. Compared with the backstepping control scheme, the proposed control scheme provides a faster convergence rate for the tracking error system. Simulation results show the effectiveness of the proposed control scheme.

IEEE International Conference on Communications in China (ICCC)

作者： Qingling Wang Changyin Sun School of Automation Southeast University Nanjing China Ministry of Education Key Laboratory of Measurement and Control of Complex Systems of Engineering Nanjing China

ISBN: (纸本)9781509002443

This paper considers the consensus problem synthesized with transient performance for a class of linear systems subject to input saturation. Two different settings, the undirected communication topology and a directed communication topologies, are systematically considered. To improve the transient performance of the resulting consensus, a saturated nonlinear consensus algorithm is proposed to solve this problem. Consensus tracking control for a class of linear systems is proved to be achieved under the general undirected and a directed graphs provided that their generated graphs contain a directed spanning tree. Numerical examples are utilized to illustrate the effectiveness of the theoretical results.

Single sample face recognition via lower-upper decomposition

Single sample face recognition via lower-upper decomposition

Asian control Conference

作者： Changhui Hu Xiaobo Lu School of Automation Southeast University Nanjing China Key Laboratory of Measurement and Control of Complex Systems of Engineering Ministry of Education Nanjing China

ISBN: (纸本)9781479978632

In this paper, a new single sample face recognition approach based on lower-upper (LU) decomposition is proposed. The single sample and its transpose are decomposed to two sets of basis images respectively by LU decomposition algorithm. Two approximation images are reconstructed from the two basis image sets respectively by the experimental estimation method. The fisher linear discriminant analysis (FLDA) is used to evaluate the optimal projection space using the new training set consisting of the single sample and its two approximation images for each person. We make two main contributions: one is that we propose to decompose the single sample and its transpose using the efficient LU decomposition algorithm; the other is that we present an experimental estimation method using the fixed image size to evaluate the number of basis images, which are used to reconstruct the approximation image. The experimental results on the FERET and AR face databases indicate that the proposed method is efficient and outperforms several state-of-the-art approaches which are proposed to address the single sample per person problem.

Results are presented of searches for continuous gravitational waves from 20 accreting millisecond x-ray pulsars with accurately measured spin frequencies and orbital parameters, using data from the third observing run of the Advanced LIGO and Advanced Virgo detectors. The search algorithm uses a hidden Markov model, where the transition probabilities allow the frequency to wander according to an unbiased random walk, while the J-statistic maximum-likelihood matched filter tracks the binary orbital phase. Three narrow subbands are searched for each target, centered on harmonics of the measured spin frequency. The search yields 16 candidates, consistent with a false alarm probability of 30% per subband and target searched. These candidates, along with one candidate from an additional target-of-opportunity search done for SAX J1808.4−3658, which was in outburst during one month of the observing run, cannot be confidently associated with a known noise source. Additional follow-up does not provide convincing evidence that any are a true astrophysical signal. When all candidates are assumed nonastrophysical, upper limits are set on the maximum wave strain detectable at 95% confidence, h095%. The strictest constraint is h095%=4.7×10−26 from IGR J17062−6143. Constraints on the detectable wave strain from each target lead to constraints on neutron star ellipticity and r-mode amplitude, the strictest of which are ε95%=3.1×10−7 and α95%=1.8×10−5 respectively. This analysis is the most comprehensive and sensitive search of continuous gravitational waves from accreting millisecond x-ray pulsars to date.

An optimal stochastic problem of production scheduling for uncertain re-entrant assembly workshops(URAWs) was studied, in which the assembly process is repeated on the basis of quality inspection result and the number of repeats is uncertain. According to analysis of URAWs, a stochastic expected value model of production scheduling was built up. In order to solve the model conveniently, the model was then converted into a deterministic model. A genetic simulated annealing algorithm based on feasible region(FR-GSAA) was designed to solve this model. Finally the result of simulation examples indicates that the model and the algorithm are feasible and practical.

In this paper, the finite-time stabilization problem for second-order systems subject to mismatched disturbances is studied. By integrating the homogeneous control technique and the finite-time disturbance observer together, a kind of feedforwardfeedback composite controllers are proposed. These controllers globally finite-time stabilize the disturbed systems. Moveover,the composite control method is also used to solve the finite-time consensus problem of leaderless second-order systems with mismatched disturbances. Simulations demonstrate the effectiveness of the proposed control algorithms.

EXPONENTIAL STABILITY OF LINEAR DISTRIBUTED PARAMETER SWITCHED systems WITH TIME-DELAY

In this paper, the exponential stability analysis for ODE switched systems with time delay is extended to distributed parameter switched systems(DPSS) in Hilbert space. For a given family of exponential stable subsystems, this paper focuses on finding conditions to guarantee the overall DPSS' exponential stability. Based on semigroup theory, by applying piecewise Lyapunov-Krasovskii functionals method incorporated average dwell time approach, sufficient conditions for exponential stability are derived. These conditions are given in the form of linear operator inequalities(LOIs)where the decision variables are operators in Hilbert space, and the stability properties depend on switching rule. Being applied to heat switched propagation equations, these LOIs are reduced to standard Linear Matrix Inequalities(LMIs). Finally, a numerical example is given to illustrate the effectiveness of the proposed result.
