Abstract: A control for a modeled plant is provided. The modeled plant is represented by a model expression that is based on an input into the plant, an output from the plant, model parameters, and an estimated value for disturbance that is applied to the plant. The model expression includes a term in which the estimated disturbance value is multiplied by at least one of the model parameters. The model parameters are identified. The estimated disturbance value is calculated so that an error between a model output that is calculated based on the model expression and an actual output of the plant is minimized. The input into the plant is calculated based on the model expression so as to control the plant. Thus, the estimated disturbance value is directly reflected in the input into the plant without being calculated by any of the model parameters.

Abstract: A supercharger of an engine comprises a motor/generator, a compressor provided in an air intake system of the engine, and a planetary gear mechanism. The planetary gear mechanism includes a sun gear connected to a driving shaft of the engine, planetary gears connected to the motor/generator and a ring gear connected to the compressor. The controller drives the motor/generator to control a rotational speed of the planetary gears. Through the control of the rotational speed of the planetary gears, a rotational speed of the compressor is controlled independently of a rotational speed of the engine. Thus, the rotation speed of the compressor can be continuously changed over a range from zero to a higher rotational speed than the engine rotational speed. Any desired supercharged pressure can be generated independently of the engine rotational speed.

Abstract: A controller for a transmission capable of preventing an occurrence of a gear squeak caused by a malfunction of a synchronization mechanism. The voltage determination section 24 performs a shift operation of a transmission by determining a control input Vin to a shift motor 13 so as to match an actual position Psc of a coupling sleeve 6 grasped by an actual position grasping section 21 with a target position Psc_cmd of the coupling sleeve 6 set by a target position setting section 22. After starting the shift operation of the transmission, it halts the shift operation by detecting a malfunction in the gear position where the shift operation is under execution when the actual position Psc of the coupling sleeve 6 has reached a malfunction judgment position provided within a range from a balk point to a contact point between the coupling sleeve 6 and an idle gear 7c before a difference Esc between the actual position Psc and the target position Psc_cmd of the coupling sleeve 6 exceeds a given contact judgment value.

Abstract: A plant controller controls a plant modeled in a discrete-time system. The controller uses a frequency-shaping response-designating control algorithm having a filtering function to cause a difference between output of the plant and a target value to converge. Thus, the plant is robustly controlled without causing undesired frequency components. When the plant is an engine, the engine is modeled using a ignition timing corrective quantity as input and a rotational speed as output. The controller performs the frequency-shaping response-designating control algorithm to determine the ignition timing corrective quantity. The frequency-shaping response-designating control may be frequency-shaping sliding-mode control. In one embodiment, the control input into the plant may includes a corrective term for stabilizing an internal variable of the filter, a corrective term for stabilizing the difference between the output of the plant and the target value and a corrective term that varies depending on a switching function.

Abstract: An apparatus for detecting an in-cylinder pressure of an engine is provided. The apparatus comprises an in-cylinder pressure sensor for outputting a signal indicating a change rate of an in-cylinder pressure and a control unit. The control unit is configured to correct the signal from the in-cylinder pressure sensor, integrate the corrected signal to determine the in-cylinder pressure, determine a change rate of a drift contained in the determined in-cylinder, and feedback the change rate of the drift so that the correction of the signal is made with the change rate of the drift. Since the output of the in-cylinder pressure sensor from which a drift has been removed is integrated, it is prevented that a drift appears in the in-cylinder pressure obtained by the integral. A resetting operation is not required so as to remove a drift.

Abstract: An air-fuel ratio control system for an internal combustion engine, which is capable of quickly and properly eliminating variation in air-fuel ratio between a plurality of cylinders. The air-fuel ratio control system 1 controls the amount of fuel to be supplied to first to fourth cylinders #1 to #4, on a cylinder-by-cylinder basis, thereby controlling the air-fuel ratio of a mixture supplied to each of the cylinders. A LAF sensor 14 delivers to an ECU 2 an output KACT indicative of the air-fuel ratio of exhaust gases emitted from the cylinders and merged. A cycle filter 23a and a rotation filter 23b filters the output KACT from the LAF sensor 14 such that components in respective bands of a first frequency fr1 and a second frequency fr2 are allowed to pass therethrough. A final fuel injection amount TOUTi is determined, on a cylinder-by-cylinder basis, according to a first filtered value KACT_Fc or a second filtered value KACT_Fr such that the amplitude of the filtered value KACT_Fc or KACT_Fr converges to a predetermined value.

Abstract: A method and an apparatus for estimating an amount of drawn air of a cylinder and a method and an apparatus for controlling the amount of drawn air, are presented. An estimated value of an amount of drawn air of the cylinder, based on intake manifold pressure, is multiplied by a value of an identification parameter obtained by an adaptive observer, to obtain a final estimated value of an amount of drawn air of the cylinder. An accurate estimated value in a transient state as well as an estimated value not oscillating in a steady state can be obtained. Accordingly, accuracy of air-fuel ratio control can be remarkably increased.
