COMBUSTION CONTROL APPARATUS

According to an embodiment, a combustion control apparatus includes a ratio setter (12), a first and a second control loops (I 0, 11 ), and a first and a second dynamic feed forward compensators (13, 14). The ratio setter (12) sets the ratio between an air flow rate (PV0) and a fuel flow rate (PV1) to be adjusted. The first control loop (I 0) includes an air flow rate (PV 0) process, and the second control loop (II) includes a fuel flow rate (PV 1) process. The first and the second dynamic feed forward compensators (13, 14) compensate for dead times in the air flow rate (PVo) process which is related to responsiveness of the first control loop (10) and in the fuel flow rate (PV1) process which is related to responsiveness of the second control loop (11) to a change in a combustion request level indicated by a master signal.
