论文摘要
在本文中,我们提出了一个基于PI的被动率控制器,适用于大量的开关电源转换器,以确保全球状态调节到所需的平衡点。在\ cite {hertal}中报告了解决此问题的解决方案,但它需要完整的状态反馈,这实际上使其变得不可行。为了克服这一限制,我们构建了一个可以在实际应用中可用的测量值来实现的国家观察员。观察者在有限的时间内重建状态,以确保PI的全球收敛性。观察者的激发要求非常弱,并且在转换器的正常操作中满足。仿真结果说明了拟议的PI的出色性能。
In this paper we propose a PI passivity-based controller, applicable to a large class of switched power converters, that ensures global state regulation to a desired equilibrium point. A solution to this problem was reported in \cite{HERetal} but it requires full state-feedback, which makes it practically unfeasible. To overcome this limitation we construct a state observer that is implementable with measurements that are available in practical applications. The observer reconstructs the state in finite-time, ensuring global convergence of the PI. The excitation requirement for the observer is very weak and is satisfied in normal operation of the converters. Simulation results illustrate the excellent performance of the proposed PI.
