在本文中,我们使用平方和(SOS)和半定规划(SDP)为一类具有点测量和点驱动的一维抛物型偏微分方程设计输出反馈控制器。我们的方法基于使用 SOS 来搜索正二次 Lyapunov 函数、控制器和观测器。这些 Lyapunov 函数、控制器和观测器由 SOS 多项式定义的线性算子参数化。本文的主要结果是开发了一种改进的基于观察者的控制器,证据表明当系统可控且可观察时,这些方法将找到一个具有足够高多项式次数的基于观察者的控制器(类似于众所周知的反步法结果)。
In this paper we use Sum-of-Squares (SOS) and Semi-Definite Programming (SDP) to design output feedback controllers for a class of one-dimensional parabolic partial differential equations with point measurements and point actuation. Our approach is based on the use of SOS to search for positive quadratic Lyapunov functions, controllers and observers. These Lyapunov functions, controllers and observers are parameterized by linear operators which are defined by SOS polynomials. The main result of the paper is the development of an improved class of observer-based controllers and evidence which indicates that when the system is controllable and observable, these methods will find a observer-based controller for sufficiently high polynomial degree (similar to well-known results from backstepping).
