    摘要: The amount of fuel injection is determined with higher accuracy. In an internal combustion engine provided with a variable valve mechanism capable of changing the amount of lift of an intake valve, a controlling device for controlling the amount of fuel injection has a means for detecting an actual lift amount (ALIFT) of the intake valve and feedback-controls the actual lift amount on a predetermined control cycle so that the actual lift amount converges to a target lift amount (ALCMD) at a predetermined time constant (τp). The controller calculates an estimated value (HALIFT) of the amount of lift in a subsequent control cycle by adding a value obtained by multiplying a difference between the target lift amount and the actual lift amount by a predetermined gain (C) to the actual lift amount. Then, the controlling device calculates, based on the estimated value of the amount of lift, the amount of fuel to be injected in the subsequent control cycle, where the gain is calculated based on the length of the control cycle and on the time constant above.

    摘要: Deterioration in response of a control subject is detected. A device for detecting deterioration in response of a control subject detects a first output and a second output that is different in kind from the first output as first and second actual measurement values on outputs of the control subject, respectively. The device is provided with a first controller that calculates a second target value of the second output so that the first actual measurement value converges on a first target value by non-linear control; and a second controller that is connected with the output of the first controller, receives the second target value and calculates an operation amount for the second actual measurement value to converge on the second target value by linear control to make the operation amount expressible as a transfer function. The operation amount is applied to the control subject. Further, the transfer function of the second controller and the transfer function of the control subject are synthesized to make a synthesized transfer function, a value obtained by applying the synthesized transfer function to the second target value is calculated as an estimated value of the second output, and deterioration in response of the control subject is detected in accordance with deviation between the estimated value and the second actual measurement value.
