摘　　要：针对Boost变换器的非线性特性,考虑变换器参数不同情况对系统模型的影响,分别建立了参数确定和参数不确定条件下Boost变换器的等价T-S模糊模型。基于建立的等价T-S模糊模型,利用Lyapunov函数方法和线性矩阵不等式方法,给出了Boost变换器并行分配补偿模糊控制器的参数化设计方法。仿真结果表明,所建立的Boost变换器T-S模糊模型是可靠的,所设计的模糊控制器与模糊PI相比具有较强的鲁棒性和抗扰性。To the Boost converter nonlinear characteristic,considering the influences caused by different parameters of the system model,T-S fuzzy models of boost converter under the condition of parameter determination and uncertainty are established respectively.According to the established T-S fuzzy model,using the common quadratic Lyapunov function（CQLF） and the linear matrix inequality（LMI）method,the design method of the fuzzy controller via parallel distributed compensation（PDC） strategy is given.Comparing the fuzzy controller with the fuzzy PI controller,the simulation results show that the proposed T-S fuzzy model of Boost converter is reliable and has better performances of robustness and immunity to disturbance than fuzzy PI controller.
