摘要： A control apparatus which is capable of compensating for a control error properly and quickly even under a condition where the control error is temporarily increased e.g. by degradation of reliability of the detection results of reference parameters other than controlled variables, thereby making it possible to ensure a high accuracy of control. An air-fuel ratio controller of the control apparatus calculates modified errors by multiplying e.g. an air-fuel ratio error estimated value by link weight functions, calculates basic local correction values such that the modified errors become equal to 0; calculates local correction values by multiplying the basic local correction values and the like by the link weight functions; calculates corrected valve lift by adding a lift correction value, which is the total sum of the local correction values, to a value of valve lift; calculates a first estimated intake air amount for feedforward control of an air-fuel ratio, based on the corrected valve lift; calculates an air-fuel ratio correction coefficient for feedback control of the air-fuel ratio; and calculates a fuel injection amount based on these.

摘要： A cam phase control system for an internal combustion engine, which is capable of suppressing deviation of the cam phase which is caused by a sudden change in the engine speed due to the structure of a variable cam phase mechanism, thereby securing excellent controllability and high control accuracy. The coma phase control system of the engine comprise an ECU and an electromagnetic variable cam phase mechanism. The ECU calculates an SLD control input for causing the cam phase to converge to a target cam phase by equations (1) to (6), calculates a gain-adjusted value by modulating the SLD control input by equations (20) to (25), calculates a correction value according to the engine speed NE, and calculates a control input for controlling the variable cam phase mechanism by correcting the gain-adjusted value by the correction value.
