Abstract: According to a sliding mode control method, a hyperplane for a sliding mode control process is established with a linear function having as variables a plurality of state quantities of an object to be controlled. The state quantities are converged onto the hyperplane, and also converged toward a balanced point on the hyperplane while the state quantities are being converged onto the hyperplane, thereby to control the state quantities at target state quantities represented by the balanced point. The hyperplane are variably established depending on the manner in which the state quantities are converged onto the hyperplane.

Abstract: An air-fuel control system for use with an internal combustion engine has a catalytic converter in an exhaust system of the engine, for purifying an exhaust gas emitted from the engine, a first exhaust gas sensor in the exhaust system for detecting an air-fuel ratio of the exhaust gas upstream of the catalytic converter, and a second exhaust gas sensor in the exhaust system for detecting the concentration of a component of the exhaust gas which has passed through the catalytic converter, downstream of the catalytic converter. A sliding mode controller determines a correction quantity at a first period to correct the air-fuel ratio of the engine so as to equalize the concentration of the component downstream of the catalytic converter to a predetermined appropriate value, according to a sliding mode control process based on the output from the second exhaust gas sensor. A feedback controller determines a correction quantity at a second period for a rate at which fuel is supplied to the engine so as to converge the concentration of the component downstream of the catalytic converter toward the predetermined appropriate value, based on the correction quantity to correct the air-fuel ratio and the output from the first exhaust gas sensor, and feedback-controls the rate at which fuel is supplied to the engine with the determined correction quantity. The first and second periods are established separately from each other.

Abstract: An exhaust gas purifying apparatus for an internal combustion engine is provided. The apparatus includes a first catalyst and a second catalyst. The first catalyst is provided in an exhaust passage of the engine, and can remove NOx in exhaust gases from the engine when an air-fuel ratio of an air-fuel mixture burning in the engine is in the vicinity of the stoichiometric ratio. The second catalyst is provided downstream of the first catalyst, an can remove NOx in the exhaust gases using a reducing agent. An execution condition of a lean operation in which the air-fuel ratio is set to a lean air-fuel ratio which is leaner than the stoichiometric ratio, is determined. When switching the air-fuel ratio from an air-fuel ratio in the vicinity of the stoichiometric ratio to the lean air-fuel ratio, the air-fuel ratio is controlled to a rich air-fuel ratio which is richer than the stoichiometric ratio, during a lean transition period from the time the execution condition is satisfied. The air-fuel ratio is controlled to the lean air-fuel ratio after the lean transition period has elapsed.

Abstract: In a control apparatus for an automatic transmission, it is configured to calculate a change amount (ΔNC estimation value) of an output rotational speed of the transmission (S10); calculate an average (I phase initial average G) of the change amount of the output rotational speed over a predetermined period of an initial inertia (I) phase of shifting; calculate an average (after-shift average G) of a vehicle acceleration after the completion of the shifting, assuming that the change amount of the output rotational speed indicates the vehicle acceleration G; calculate a difference (I phase initial G) between the average of the change amount of the output rotational speed and the average of the vehicle acceleration; incrementally and decrementally correct the desired value of the transmission torque of the frictional engaging element such that the calculated difference falls within a predetermined range; and control supply of hydraulic pressure to the frictional engaging element such that it becomes the corrected desired value (S14 to S20). With this, since the vehicle acceleration at shifting is estimated and evaluated and based thereon, variation in the transmission torque of the frictional engaging element, etc., is learned, it becomes possible to fully exploit the potential of the frictional engaging element, thereby improving a feel given to the vehicle occupant(s) at shifting.

Abstract: A control apparatus that can partially identify model parameters is provided. The apparatus for controlling an object that is modeled using at least one first model parameter and at least one second model parameter comprises a partial model parameter identifier for recursively identifying the second model parameter based on an output from the object and an input into the object, and a controller for using the first model parameter that is pre-identified and the second model parameter identified by the partial model parameter identifier to determine an input into the controller so that the output from the object converges to a desired value. Since all model parameters are not required to be recursively identified, the time for causing the model parameters to converge to optimal values can be shortened. The computational complexity for the identifier can be reduced.

Abstract: An exhaust gas purifying apparatus for an internal combustion engine having a lean NOx catalyst in an exhaust system is provided. The lean NOx catalyst traps NOx in exhaust gases when the exhaust gases are in an oxidizing state, and discharges the trapped NOx when the exhaust gases are in an reducing state. In this apparatus, an estimated trapped NOx amount which is an estimated value of an amount of NOx trapped in the lean NOx catalyst, is calculated using a neural network. Engine operating parameters indicative of an operating condition of the engine are input, and the neural network outputs at least one control parameter which is relevant to the lean NOx catalyst. A reducing process of the NOx trapped in the lean NOx catalyst is performed according to the estimated trapped NOx amount.

Abstract: An exhaust gas purifying apparatus for an internal combustion engine is provided. A selective reduction catalyst is disposed in an exhaust passage of the engine for reducing NOx in exhaust gases from the engine under existence of a reducing agent. The reducing agent or a reactant for generating the reducing agent is supplied to the upstream side of the selective reduction catalyst. Occurrence of a reducing-agent slip in which the reducing agent is discharged to the downstream side of the selective reduction catalyst is determined. A storage amount indicative of an amount of the reducing agent stored in the selective reduction catalyst is temporarily reduced from the state where the storage amount is at the maximum, and thereafter the storage amount is increased until the occurrence of the reducing-agent slip is detected. A supply correction amount for correcting an amount of the reducing agent is calculated according to an occurrence state of the reducing agent slip when the storage amount is changed. A basic supply amount of the reducing agent is calculated according to an operating condition of the engine or a NOx concentration on the upstream side of the selective reduction catalyst. A supply amount of the reducing agent is calculated by correcting the basic supply amount using the supply correction amount.
