UCG Simulator Integration with MATLAB For Control Purpose

#Modelling #Paradigm #UCG #CAVSIM #Ansys #Comsol #Solidworks

Mathematical modelling and simulation serve as a cornerstone for both the academic and industrial sectors. A well-developed model helps the user analyze the behaviour of the physical process, make predictions about the system's output, and develop a controller to guide the system's trajectories. However, capturing the overall dynamics subsequently leads to a model structure that is non-linear in behavior and Multiphysics in nature. Such complex structures are significantly harder to analyze and solve. The general workflow of a modelling paradigm spans several steps, and it rarely occurs, as far as practical problems are concerned, that an individual or a group assumes the responsibility of all the steps. The tasks are distributed among the dedicated and specialized groups, which, with interactive and joint collaboration, come up with Mathematical modelling and simulation serve as a cornerstone for both the academic and industrial sectors.

The tasks are distributed among the dedicated and specialized groups, which, with interactive and joint collaboration, come up with a model of the physical process under observation. Moreover, with the increasing computing power and the advent of computational software, such as Ansys, Comsol, and Solidworks, etc., they have assisted in the development, analyzing, and solution of mathematical problems. However, each of these programmes is limited in the types of problems it can handle, and there is no all-encompassing software that can meet all of the needs of a design engineer. In this regard, it is crucial to develop an ad hoc interface between such software to establish at least a unidirectional communication channel. CAVSIM is a simulator that can simulate the UCG process for a variety of compositions and stratigraphies of coal and overburden. It was developed by Lawrence National Laboratories, and the model is written in Fortran. However, this platform provides next to none tools to design a controller. MATLAB, on the other hand, has built-in functionalities that lend themselves to the streamlined synthesis of a controller. Therefore, to pose and solve the UCG system under the unified umbrella of a control problem, an integration between CAVSIM and MATLAB was called for.
