Control apparatus and method

摘要

A control apparatus capable of ensuring high control accuracy even if a controlled object is in a transient state, when a control input (Tout) is calculated based on a value obtained by correcting a value (Tibs) calculated by a feedforward control method (30) using a value (KAF) calculated by a feedback control method (20). The control apparatus calculates a fuel correction coefficient (KAF) such that an output from an oxygen concentration sensor (VO2) converges to a target output (VO2_TRGT), and multiplies a basic injection amount (Tibs) by the coefficient (KAF) to calculate a fuel injection amount (Tout). The feedforward control (30) calculates a modification value for making the correction coefficient (KAF) equal to a predetermined target value.
