    摘要： A controller for a plant that controls a controlled variable for the plant in accordance with estimated values, allowing to reduce any error in the estimated values that is caused by solid variation or aging of the plant. A controller for an exhaust emission control system has an estimated Inert-EGR value calculation section (711) to calculate the estimated value IEGRHAT for the Inert-EGR amount on the basis of an input vector U through a neural network, an estimated LAF sensor output value calculation section (712) to calculate the estimated value ΦHAT for an exhaust air-fuel ratio correlating with the Inert-EGR amount on the basis of the input vector U through the neural network, an LAF sensor (34) to detect the exhaust air-fuel ratio, and a nonlinear adaptive corrector (713) to calculate the adaptive input UVNS such that the estimated error EHAT between the detected value ΦACT from the LAF sensor (34) and the estimated output value ΦHAT of the LAF sensor (34) is minimized.

    摘要： A control apparatus capable of improving the control accuracy and stability when controlling a controlled object with a predetermined restraint condition between a plurality of model parameters, or a controlled object having a lag characteristic, using a control target model of a discrete-time system. The control apparatus has an ECU which arranges a control target model including two model parameters such that terms not multiplied by the model parameters and terms multiplied by the same are on different sides of the model, respectively. Assuming the different sides represent a combined signal value and an estimated combined signal value, respectively, the ECU calculates onboard identified values of the model parameters such that an identification error between the signal values is minimized, and calculates an air-fuel ratio correction coefficient using the identified values and a control algorithm derived from the control target model.

    摘要： A control apparatus which is capable of enhancing the accuracy of control of a controlled object having characteristics that dead time and response delay thereof vary. The control apparatus includes an ECU. The ECU calculates four predicted values as values of a controlled variable associated with respective times when four dead times elapse, respectively, calculates four weight function values associated with an exhaust gas volume, and calculates four products by multiplying the predicted values by the weight function values, respectively. The ECU sets the total sum of the four products as a predicted equivalent ratio and calculates an air-fuel ratio correction coefficient such that the predicted equivalent ratio becomes equal to a target equivalent ratio.

    摘要： 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. An accuracy of the reducing agent supply is determined according to an occurrence state of the reducing agent slip when the storage amount is changed.
