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: A low cost control apparatus of a contact mechanism resolving a disadvantage caused when a contact body is moved to make contact with a contacted body by an actuator. A synchronizing mechanism, which a coupling sleeve rotatably and integrally provided with an input shaft is pushed against a synchronizer ring disposed between the coupling sleeve and a synchronized gear, thereby synchronizing rotational speeds of both the components to engage them, is modeled as a collision between an inertia system object and an elastic system object. A computation coefficient (VPOLE, f in FIG. 9) of a switching function for sliding mode control having a deviation between an actual position of the coupling sleeve (Psc, d in FIG. 9) and a target position (Psc_cmd, e in FIG. 9) as a state variable is changed depending on the actual position (Psc), and thereby changing a control ability of the model against a disturbance.

Abstract: Misfire of an engine is detected by extracting a pressure component of combustion from an output of a pressure sensor disposed in a cylinder. An engine misfire detection apparatus obtains a combustion parameter Cr that is a correlation between a reference signal Fc synchronous with the combustion cycle of the engine and cylinder pressure Pc obtained from an output of a pressure sensor disposed in the cylinder. The apparatus detects a misfire of the engine based on the combustion parameter. A misfire can be accurately detected even under a low load condition because the combustion parameter indicating the combustion component is extracted from the cylinder pressure as a correlation between the reference signal synchronous with the combustion cycle of the engine and the cylinder pressure obtained from the sensor output. The combustion parameter is a sum of products of discrete values Pc(i) of the cylinder pressure which are obtained at a predetermined rate and discrete values Fc(i) of the reference signal.

Abstract: A control system for a plant is provided. This control system can control the plant more stably, when the model parameters of the controlled object model which are obtained by modeling the plant, which is a controlled object, are identified and the sliding mode control is performed using the identified model parameters. The model parameter identifier (22) calculates a model parameter vector (θ) by adding an updating vector (dθ) to a reference vector (θbase) of the model parameter. The updating vector (dθ) is corrected by multiplying a past value of at least one element of the updating vector by a predetermined value which is greater than “0” and less than “1”. The model parameter vector (θ) is calculated by adding the corrected updating vector (dθ) to the reference vector (θbase).

Abstract: An ignition timing control system for internal combustion engines, which is capable of preventing occurrence of variation in engine speed and vibrations which can be caused due to variation in combustion state between the cylinders, to thereby improve drivability. The ECU 2 of the ignition timing control system 1 calculates a statistically processed value Pmi_ls#i according to the in-cylinder pressure Pcyl#i, and calculates an averaging target value Piav_cmd by weighted averaging of a minimum value Pmi_ls_min1 and a second minimum value Pmi_ls_min2 within a predetermined range of the statistically processed value. The ECU 2 calculates a correction value DIGCMP#i by performing a limiting process for setting the optimization correction value DIGOP#i for control of the ignition timing to a limit value on the advanced side, on the averaging correction value DIGPIAV#i for causing the statistically processed values Pmi_ls#i to follow the averaging target value Piav_cmd, such that the statistically processed values Pmi_ls#i becomes maximum. The ignition timing IGLOG#i is calculated for each cylinder based on the correction value DIGCMP#i.
