| 摘 要： | 根据Buck-Booat变换器的工作原理及其非线性特征,在电感电流连续导通模式和断续导通模式下,分别对Buck-Boost 电路构建T-S模糊模型,在断续导通模式下,引入切换函数,统一了两种模式下电路状态方程和T-S模糊模型.仿真结果表明,Buck-Boost变换器经T-S建模后,输出电压平均值和电感电流的平均值的误差均在2%以内,符合实际应用的要求.T-S模糊建模的有效性和可行性得到验证.

| Abstract: | According to the basic principle and the non-linear characteristic of the Buck-Boost converter,this paper separately con- structs the T-S fuzzy model of the Buck-Boost electric circuit under two patterns which are CCM and DCM.In order to uniform the cir- cuit state equation and T-S fuzzy model under these two patterns,this paper introduces the switching function in DCM.The average output voltage and the average inductor current errors of the Buck-Boost converter in T-S fuzzy model are within 2%,in line with the actual application requirements.The effectiveness and feasibility of T-S fuzzy modeling is verified. |
