表2 不同工作模态下的系统状态方程

Tab.2 System state equations in different working modes

工作模态	状态表达式
模态1	L_sc $\frac{d i_{s c}}{d t}$ =u_g-u_L+u_dcn, L_pc $\frac{d i_{p c}}{d t}$ =u_L+u_dcp
模态2	L_sc $\frac{d i_{s c}}{d t}$ =u_g-u_L-u_dcp, L_pc $\frac{d i_{p c}}{d t}$ =u_L+u_dcp
模态3	L_sc $\frac{d i_{s c}}{d t}$ =u_g-u_L-u_dcp, L_pc $\frac{d i_{p c}}{d t}$ =u_L-u_dcn
模态4	L_sc $\frac{d i_{s c}}{d t}$ =u_g-u_L+u_dcn, L_pc $\frac{d i_{p c}}{d t}$ =u_L-u_dcn
