on stability and application of extremum seeking control without steady state oscillation
Automatica, 2016Co-Authors: Libin Wang, Songlin ChenAbstract:To enhance the dynamic and static performance of the extremum seeking control (ESC) scheme, a novel fast ESC scheme without steady-state oscillation is proposed, in which the structure of the classic ESC scheme is adjusted to make the Sinusoidal Excitation signal amplitude locally exponentially converge to zero. The improved ESC scheme can speed up the convergence to shorten the seeking time dramatically, and enlarge the search area to avoid falling to local extrema effectively. It can also reduce the Sinusoidal Excitation signal amplitude to eliminate the adverse effects of the steady-state oscillation eventually. The rigorous stability analysis and proof of the improved ESC scheme are provided in detail, and the simulation results are presented to illustrate its effectiveness and superiority. Finally, the application of the improved ESC scheme to antilock braking systems (ABS) has been discussed through comparing with classical perturbation-based ESC scheme and sliding-mode-based ESC scheme to illustrate the practicability of the improved scheme.

a novel fast extremum seeking scheme without steady state oscillation
Chinese Control Conference, 2014Co-Authors: Libin Wang, Songlin Chen, Hui ZhaoAbstract:To enhance the dynamic and static performance of the extremum seeking scheme (ESS), a novel fast ESS without the steady-state oscillation is proposed by adjusting the structure of the classic ESS to make the Sinusoidal Excitation signal amplitude proportional to the absolute value of the extremum estimation error. The improved ESS can speed up the convergence to shorten the seeking time dramatically, and enlarge the search area to avoid falling to the local extremum effectively. It can also reduce the Sinusoidal Excitation signal amplitude to eliminate the adverse effects of the steady-state oscillation eventually. The stability analysis and proof of the improved ESS are provided in detail, and the enormous simulation results, compared with the other ESS, are presented to illustrate its effectiveness and superiority.

Simulation of PMBLDC Motor With Sinusoidal Excitation Using Trapezoidal Control Strategy
2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006Co-Authors: R. Somanatham, P.v.n. Prasad, A. RajkumarAbstract:The work reported concern with the simulation of a sensor controlled PMBLDC motor for Trapezoidal and Sinusoidal Excitations. For both types of Excitations Trapezoidal current control strategy is adapted. The simulated model is used to study the variation of speed, torque and current for various loads. A comparative study has been made for both types of Excitations. The dynamic response was found to be better with Trapezoidal Excitation than with Sinusoidal Excitation on no-load. However, for steady state operation on load, Sinusoidal Excitation was seen to be better.

Effect of Non-Sinusoidal Excitation to Inrush Current for Transformer
2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006Co-Authors: Chien-lung Cheng, Shyi-ching Chern, Jim-chwen Yeh, Y. HuangAbstract:Inrush current is an important issue for transformers security and stability. Harmonic effects in power systems have been significantly increasing in the last decade. In this paper, SINm(omegat) waveforms represent non-Sinusoidal waveforms because studies on SINm(omegat) waveforms appear to be simpler for more predictable results. A flux analysis of single-phase transformer is proposed in this paper. Furthermore, an active suppression method of inrush current is proposed. Finally, the effect of non-Sinusoidal Excitation to inrush current is analyzed and discussed in detail
