基于部分状态反馈的燃料电池系统协同滑模控制
Coordinated Sliding Mode Control of Fuel Cell Systems Based on Partial State Feedback
摘要
Abstract
Proton exchange membrane fuel cell(PEMFC)has emerged as an ideal alternative to traditional intern-al combustion engines due to their high efficiency and clean characteristics.Within PEMFC systems,the oxygen ex-cess ratio and cathode pressure in the air supply subsystem are critical variables that affect performance and durab-ility.However,these variables are often not directly measurable in practical applications,and the system model is subject to parameter uncertainties.To address these challenges,this paper proposes a partial state feedback co-ordinated control strategy with a prescribed time.The core of this strategy is the innovative design of"guidance variables",which depend solely on measurable states and target setpoints.By leveraging input-to-state stability the-ory,the original control problem is transformed into a stabilization problem for"guidance variables".Subsequently,a sliding surface is constructed as a linear combination of"guidance variables"and their derivatives.Building upon this,an adaptive sliding mode control law based on a barrier Lyapunov function is proposed.This ensures that the sliding variable converges to a specified small neighborhood within a prescribed time,thereby achieving indirectly precise control of the oxygen excess ratio and cathode pressure while the measurement noise vanishes.This method circumvents the need for direct measurement of critical states and does not rely on an exact system model paramet-er.Both simulation and hardware-in-the-loop experimental results validate that the proposed strategy exhibits ex-cellent dynamic response and strong robustness against parameter uncertainties.关键词
