Temperature Estimation Model for Solid Oxide Fuel Cell Based on Luenberger-sliding Mode Observer
摘要
Abstract
As a new type of power generation device,solid oxide fuel cell(SOFC)has a broad application prospect in various fields in the future due to its advantages of high efficiency,no pollution,all-metal solid structure and wide fuel source.The temperature distribution inside a reactor is very important for its safe and stable operation.It is difficult to obtain the internal temperature,and with the aim of solving this problem,a Luenberger-sliding mode observer is designed to estimate the internal temperature distribution.First,the observability of the system and engineering application are considered for the input of the observer,and the optimal combination is selected by combining the observable matrix condition number.Then,the observer structure is constructed based on Luenberger and sliding mode observer theory.Secondly,in order to improve the performance of the observer,the stack error system is decoupled and the feedback gain is reconstructed by pole assignment.Finally,the observer buffeting phenomenon is suppressed by smoothing the nonlinear discontinuities.The simulation results show that the designed observer has obvious advantages in convergence rate and error fluctuation compared with Luenberger and sliding mode observers.关键词
