However, due to the Doppler centroid variation along the range direction, azimuth spectrum will cross into the neighboring pulse repetition frequency (PRF) band causing severe azimuth ambiguity. Conventional frequency focusing method cannot directly used in this case. In this paper, deramping technique is employed to realize the coarse focusing and reduce the azimuth bandwidth, thus spectrum folding is mitigated. Incorporated secondary range compression, fine focusing is obtained. Simulation results validate the effectiveness of the proposed method.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].

A cooperative dynamic surface control design approach is proposed to devise the formation tracking controllers, where nonlinearly-parameterized neural networks are used to compensate for the model uncertainties. It is proved that with the developed controllers, formation among vehicles can be reached if the trajectory has directed paths to all follower vehicles. Based on Lyapunov stability analysis, all signals in the closed-loop system are guaranteed to be uniformly ultimately bounded, and formation tracking errors converge to a small neighborhood of the origin. Simulation results are given to show the efficacy of the proposed method.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].

With the employment of a newly state transformation and a high-gain observer, the one-link robot system is transformed into a norm form, and then only one NN is employed to approximate the lumped uncertain system nonlinearity in the adaptive control design. Partial persistent excitation (PE) condition of radial basis function (RBF) NNs is satisfied during tracking control to a recurrent reference trajectory. Under the PE condition, the proposed adaptive NN control is shown to be capable of acquiring knowledge on the uncertain robot dynamics in the stable control process and of storing the learned knowledge in memory. Subsequently, a novel neural learning control technique exploiting the learned knowledge without readapting to the unknown robot dynamics is developed to achieve closed-loop stability and improved control performance. Simulation studies are performed to demonstrate the effectiveness of the proposed control technique.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].

A set of partial-ordinary differential equations (PDEs-ODEs) are developed by using the Hamilton's principle to describe the motion of the three-dimensional string system. The dynamic model considers the comprehensive effects of environmental loads, which are critical for the analysis of a string system. Based on the Lyapunov's direct method and the properties of the string system dynamics, three boundary control inputs are applied at the boundary to suppress the vibrations of the system under the external disturbances. Uniformly boundedness of the three-dimensional dynamics with the proposed control is achieved. Exponential stability is proved via the Lyapunov's direct method when there is no distributed disturbance. Simulation examples are provided by using the finite difference method, and some useful conclusions are drawn.","PeriodicalId":90521,"journal":{"name":"IEEE International Conference on Systems Biology : [proceedings].

For a fixed distance between the sensors to the underwater target, the MSE is minimized if and only if the determinant of the FIM is maximized. The main contribution in this paper is the dependence of the range measurement error on the acoustic propagation distance because of the complex underwater environment, which result in a different FIM expression compared to the ideal assumption case.
