    Abstract: A control input (DUT) for controlling a heater (13) which heats an active element (10) of an exhaust gas sensor (8) includes at least one of another component depending on the difference between temperature data of the active element (10) and a target temperature, a component depending on the target temperature, and a component depending on the temperature data of the active element (10). The control input is determined by an optimum control algorithm. A component depending on the temperature of an exhaust gas and the component depending on the target temperature are determined based on a predictive control algorithm. The temperature of the active element (10) of the exhaust gas sensor (8) is thus controlled stably at a desired temperature.

    Abstract: A method of calculating the amount of work done by an internal combustion engine, which is capable of calculating a work amount parameter indicative of the amount of work done with accuracy while compensating for a phase delay in in-cylinder pressure data caused e.g. by a filtering process performed thereon. The method calculates the work amount parameter Pmi indicative of the amount of work done by the engine 3 including a combustion chamber 3b, as follows: Pressure in the combustion chamber 3b is detected to obtain in-cylinder pressure data P indicative of the detected pressure. Volume data V indicative of a state of change in volume of the combustion chamber 3b is obtained. The obtained volume data V is subjected to a first predetermined filtering process. The work amount parameter Pmi is calculated based on the detected in-cylinder pressure data P, and the volume data filtered value VF obtained by subjecting the volume data V to the first filtering process.

    Abstract: A valve timing control system for an internal combustion engine, which is capable of accurately and delicately controlling an amount of intake air, and thereby maintaining excellent combustion state and reduced exhaust emissions. The valve timing control system variably controls the valve-closing timing of an intake valve with respect to valve-opening timing of the same as desired via a variable intake valve actuation assembly. The ECU of the engine determined a basic value of a target auxiliary intake cam phase according to the demanded drive torque of the engine. The ECU calculates a control input to the variable intake valve actuation assembly such that the cylinder intake air amount converges to a target intake air amount and at the same time the auxiliary intake cam phase is constrained to the basic value of the target auxiliary intake cam phase.

    Abstract: A control apparatus which is capable of ensuring both high-level stability and accuracy of control, even when controlling a controlled object having extremal characteristics or a controlled object a controlled object model of which cannot be represented. The control apparatus 1 includes a cooperative controller 30, an onboard model analyzer 40, and a model corrector 60. The model corrector 60 calculates the model correction parameter matrix θ, so as to correct the controlled object model defining the relationship between the intake opening angle θlin and the exhaust reopening angle θrbl and the indicated mean effective pressure Pmi. The onboard model analyzer 40 calculates first and second response indices RI1 and RI2 representative of correlations between θlin, θrbl, and Pmi, based on the controlled object model corrected using θ. The cooperative controller 30 calculates the θlin and θrbl such that Pmi is caused to converge to a target value Pmi_cmd, and determines an increasing/decreasing rate and increasing/decreasing direction of θlin and θrbl according to RI1 and RI2.
