具有分布控制和观测的室温模型的鲁棒输出跟踪

Robust Output Tracking for a Room Temperature Model with Distributed Control and Observation

Konsta Huhtala, Lassi Paunonen, Weiwei Hu

摘要:

我们考虑了一个描述房间温度演化的偏微分方程模型的鲁棒输出调节。更准确地说,我们研究了一个二维的房间模型的速度场和温度的演变由不可压缩的稳态Navier-Stokes方程和对流-扩散方程,分别耦合在一起形成一个简化的Boussinesq方程。我们假设我们的系统的控制和观测算子是分布的,而干扰作用于系统的边界的一部分。我们解决了鲁棒输出调节问题,使用有限维低阶控制器,这是使用模型降阶的有限元近似模型。通过数值模拟,我们比较了降阶控制器的性能,没有模型降阶的控制器,以及低增益鲁棒控制器的性能。

英文摘要:

We consider robust output regulation of a partial differential equation model describing temperature evolution in a room. More precisely, we examine a two-dimensional room model with the velocity field and temperature evolution governed by the incompressible steady state Navier-Stokes and advection-diffusion equations, respectively, which coupled together form a simplification of the Boussinesq equations. We assume that the control and observation operators of our system are distributed, whereas the disturbance acts on a part of the boundary of the system. We solve the robust output regulation problem using a finite-dimensional low-order controller, which is constructed using model reduction on a finite element approximation of the model. Through numerical simulations, we compare performance of the reduced-order controller to that of the controller without model reduction as well as to performance of a low-gain robust controller.
