Abstract
Description
if(e_fr_tbbf(k)<MIF)then if(ng_frpsr>MIF)then z(k)=a2*(1-(1/MIF))*nc_bfr+b2 else z(k)=(a2*(1-(1/MIF))*nc_gfr+b2)/c2 end if end if其中
if(e_cgsr(k)>0)then if(iw(k)>w(k))then iw(k+1)=w(k) z(k)=0 else if(w(k)>thresh1) z(k)=k6*CSRg_index else z(k)=k7*CSRg_index end if end if CSRg_index=CSRg_index+1 end if其中,w(k)在当前目标门限电平,而iw(k)为瞬时门限。在一个优选实施例中,k6=30,k7=10,而thresh1=标称目标门限电平(视硬件和系统而定)。调整量z(k)输出给相加器803。相加器803将当前目标门限减去调整量z(k),产生更新了的目标门限。
if(e_cgfr(k)>0)then if(iw(k)>w(k))then iw(k+1)=w(k) z(k)=0 else if(w(k)>thresh1) z(k)=k3*CFRg_index else z(k)=k4*CFRg_index end if end if CFRg_index=CFRg_index+1其中,w(k)在当前目标门限电平,而iw(k)为瞬时门限。在本优选实施例中,k3=50,k4=30,而thresh1=标称目标门限电平(视硬件和系统而定)。调整量z(k)输出给相加器803。相加器803将当前目标门限减去调整量z(k),产生更新了的目标门限。
if(nc_bsr>thresh2)then z(k)=k5*nc_bsrend if
if(nc_bsr>thresh2)then iz(k)=SR_StepUp end if其中,SR-StepUp为加到瞬时门限上的增量,在本优选实施例中设置为30。
