Abstract: Work done by an engine can be accurately calculated regardless of the part in an observation section where the cylinder internal pressure signal is detected. The apparatus for calculating the work done by an engine establishes in advance correlation of phase between the cylinder internal pressure of the engine and a reference signal composed of a predetermined frequency component as a reference phase relation. A means for detecting the cylinder internal pressure of the engine for a predetermined observation section is provided. A reference signal corresponding to the detected cylinder internal pressure of the engine is calculated so that the reference phase relation is satisfied. A correlation coefficient of the detected cylinder internal pressure of the engine and the calculated reference signal is calculated for the observation section and the work done by the engine is calculated in accordance with the correlation coefficient.

Abstract: There are provided a control device, a control method, a control unit, and an engine control unit, which are capable of controlling a controlled object with relatively large phase delay and dead time, while attaining elimination of lag in control timing between the input and output of the controlled object and improvement of control accuracy at the same time. A state predictor calculates a deviation (output deviation) between an output from an oxygen concentration sensor and a predetermined target value at a predetermined deviation calculation period. Then, a DSM controller calculates a target air-fuel ratio for converging the output from the oxygen concentration sensor to the predetermined target value, according to the calculated deviation, based on any one of a Δ modulation algorithm, a ΔΣ modulation algorithm, and a ΣΔ modulation algorithm at a predetermined calculation period shorter than the predetermined deviation calculation period.

Abstract: There is provided a control method for sufficiently compensating the non-linear characteristic for a plant having a strong non-linear characteristic and satisfying the follow-up and stability for a plant having a large control amount fluctuation. There is provided a plant control device using modulation algorithm. The control device includes: means for calculating a temporary control input for controlling the plant output to a target value; means for dividing the temporary control input into a plurality of components; means for modulating at least one of the components; and means for adding the modulated component to another component so as to generate a control input. Thus, it is possible to minimize the input fluctuation caused by modulation while maintaining the compensation ability of the non-linear characteristic such as plant friction and hysteresis attributed to the conventional modulation algorithm. Accordingly, even in a plant in which the temporary control input is greatly changed, it is possible to prevent oscillation of the output, thereby improving the controllability.

Abstract: A control system for an internal combustion engine, which is capable of enhancing the accuracy of fuel control and ignition timing control even when there is a possibility that the reliability of a calculated intake air amount lowers, and enables reduction of manufacturing costs. An ECU of the control system calculates a first estimated intake air amount according to a valve lift, a cam phase, and a compression ratio, calculates a second estimated intake air amount according to the flow rate of air detected by an air flow sensor. The ECU determines a fuel injection amount according to the first estimated intake air amount when an estimated flow rate Gin_vt calculated based on an engine speed, the valve lift, the cam phase, and the compression ratio is within the range of Gin_vt≦Gin1, and according to the second estimated intake air amount when Gin2≦Gin_vt.
