摘要： A control system for an internal combustion engine includes a canister for adsorbing evaporative fuel generated in the fuel tank, a purging passage extending between the canister and the intake system, for purging evaporative fuel into the intake system, and a purge control valve for controlling a flow rate of evaporative fuel to be supplied to the intake system through the purging passage. Various sensors detect operating conditions of the engine, and an ECU controls the purge control valve according to detected operating conditions. An amount of fuel to be supplied to the engine is feedback-controlled by calculating a feedback control amount, based on an output from an air-fuel ratio sensor arranged in the exhaust system by using a controller of a recurrence formula type, and the amount of fuel to be supplied to the engine is controlled based on the calculated feedback control amount, such that an air-fuel ratio of an air-fuel mixture supplied to the engine is converged to a desired air-fuel ratio. An average value of the feedback control amount is calculated while the purge control valve is open. The purge control valve is controlled based on the calculated average value.

摘要： A fuel metering control system for an internal combustion engine including a feedback loop having an adaptive controller and an adaptation mechanism that estimates controller parameters .theta.. The adaptive controller corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of said air/fuel ratio sensor, to a desired value. The adaptation mechanism is input with the controlled variable once per prescribed crank angle such as a TDC of a certain cylinder and estimates the controller parameters. Since, however, the input is limited to a specific cylinder's air/fuel ratio, the air/fuel ratio is averaged for all cylinders and used in the calculation. Similar averaging is made for the other parameters input to the mechanism or output from the controller.

摘要： A fuel metering control system for an internal combustion engine including a feedback loop having an adaptive controller and an adaptation mechanism that estimates a controller parameters .theta.. The adaptive controller corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of said air/fuel ratio sensor, to a desired value. The adaptation mechanism is input with the controlled variable once per prescribed crank angle such as TDC of a certain cylinder and estimates the controller parameters (vector). The adaptive controller is therefore operated to synchronize with every prescribed crank angle, e.g., every TDC of all cylinders of the internal combustion engine. With the arrangement, the system enables adaptive control of a commercially practical internal combustion engine without degrading control performance.

摘要： An air/fuel ratio feedback control system with the adaptive controller. The adaptive controller has a system parameter estimator which identifies system parameters such that the error between the desired value and the controlled variable outputted from the plant decreases to zero. In the system, a basic fuel injection amount is determined at a feedforward system. The adaptive controller is placed outside of the basic fuel injection amount determining system and receives the desired value (air/fuel ratio) and the controlled value (detected air/fuel ratio) using the system parameters etc. The calculated feedback coefficient is multiplied to the basic fuel injection amount to determine a final injection amount to be supplied to the plant (engine). Variables necessary for the system parameter calculation are limited their change of range so as to make the controller to be realized on a low performance computer with a small word length.

摘要： A system for controlling fuel metering for a multi-cylinder internal combustion engine, having a feedback loop which has an adaptive controller and an adaptation mechanism coupled to the adaptive controller for estimating controller parameters .theta.. The adaptive controller calculates a feedback correction coefficient using internal variables that include the controller parameters .theta., to correct a basic quantity of fuel injection obtained by retrieving mapped data by engine speed and engine load, to bring a detected air/fuel ratio to a desired air/fuel ratio. In the system, the internal variables of the adaptive controller are determined in response to detected engine operating conditions, when the engine operation has shifted from an open-loop control region to the feedback control region.

摘要： An air-fuel ratio control system for an internal combustion engine having first and second catalytic converters arranged in the exhaust passage comprises first to third exhaust gas component concentration sensors arranged in the exhaust passage, the first one being arranged upstream of the first catalytic converter, the second one at a location intermediate between the first and second catalytic converters, and the third one downstream of the second catalytic converter. An ECU carries out feedback control of the air-fuel ratio of a mixture supplied to the engine to a desired air-fuel ratio in response to an output from the first exhaust gas component concentration sensor. A first feedback control parameter for use in the feedback control is calculated, based on an output from the second exhaust gas component concentration sensor.

摘要： A system for controlling fuel metering for an internal combustion engine having a feedback system which has a controller for calculating a feedback correction coefficient, using an adaptive control law to correct a quantity of fuel injection such that a detected air/fuel ratio is brought to a desired air/fuel ratio. In the system, it is discriminated whether the feedback correction coefficient and the detected air/fuel ratio are in phase, and the feedback system is instable when they are discriminated to be in phase. Since the coefficient acts to correct the deviation of the detected air/fuel ratio from the desired air/fuel ratio, they are normally in antiphase. It is thus possible to find the system instable, by discriminating whether they are in phase or not.
