Temporal-Spatial Optimal Tracking Control of Microwave Heating Process Based on the Spectral Galerkin Method
Authors: , , ,
Abstract: Microwave heating, which is a novel and efficient heating method, has been gradually replacing traditional heating method in industrial application. However, the phenomenon of hotspots or thermal runaway is the major drawback for further development. Consequently, it is necessary to regulate the spatial temperature distribution with a reasonable input power. For traditional microwave heating partial differential equation (PDE) model, the inherent infinite-dimensional feature does not allow readily designing corresponding controller. Motivated by this obstruction, a finite-dimensional ordinary differential equation (ODE) model is developed to approximately describe the heating process with the help of spectral Galerkin method. Moreover, an optimal tracking controller with a constrained input is designed to improve the spatial temperature uniformity. Finally, the results of simulation on one-dimensional microwave cavity heating model are provided to demonstrate the effectiveness of proposed controller.
