Abstract

In this paper, we advance a nonlinear control design concept based on backstepping, adjusted so that it might be used for a wider class of dynamical systems than the so-called strict-feedback form. Possible applications concern magnetic levitation systems, one of which will be used, in this paper, to design the proposed controller. Theoretical aspects regarding feasibility, stability and optimality will be readily described in a constructive and systematical manner, emphasizing flexibility of this procedure and further extensions. Special attention is being payed to practical concerns like singularity avoidance inside feedback loop. Lastly, we deal with sine wave tracking problem, by actually comparing simulation results, with other linear and nonlinear control design techniques already existing in the literature, in terms of robustness and performance. We hope to show that, our ‘engineer’ controller synthesis proves interesting enough, by effectively manipulating theoretical concepts with numerical applicability.
磁悬浮系统正弦波跟踪控制器设计:对比仿真研究
在本文中,我们提出了一种基于反演的非线性控制设计概念,调整后使其可以用于比所谓的严格反馈形式更广泛的动力系统。可能的应用涉及磁悬浮系统,本文将使用其中一个来设计所提出的控制器。关于可行性、稳定性和最优性的理论方面将以建设性和系统的方式加以描述,强调这一程序的灵活性和进一步的扩展。特别注意的是实际问题,如奇点避免内部反馈回路。最后,通过将仿真结果与文献中已有的其他线性和非线性控制设计技术在鲁棒性和性能方面进行比较,我们处理了正弦波跟踪问题。我们希望表明,我们的“工程师”控制器合成证明了足够有趣,通过有效地操纵具有数值适用性的理论概念。
