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 in-cylinder pressure sensor outputs a signal corresponding to a change rate of an internal cylinder pressure of an engine. The output signal of the in-cylinder pressure sensor is filtered so that frequency components lower than frequencies that substantially compose an internal cylinder pressure required for controlling the engine are cut. The filtered output signal is integrated to determine the internal cylinder pressure. Thus, an internal cylinder pressure having no drift can be determined.

Abstract: The present invention provides a controller for controlling a modeled plant robustly against disturbance. The controller comprises an estimator and a control unit. The estimator estimates disturbance applied to the plant. The control unit determines an input to the plant so that an output of the plant converges to a desired value. The input to the plant is determined to include a value obtained by multiplying the estimated disturbance by a predetermined gain. Since estimated disturbance is reflected in the input to the plant, control having robustness against disturbance is implemented. The controller may comprise a state predictor. The state predictor predicts the output of the plant based on the estimated disturbance and dead time included in the plant. The control unit determined the input to the plant so that the predicted output converges to a desired value. Since the state predictor allows for the dead time, the accuracy of the control is improved. The estimated disturbance is reflected in the predicted output, an error between the predicted output and an actual output of the plant is removed.

Abstract: A controller which is capable of improving the resolution and accuracy of control even when controlling a plant including a control region in which nonlinearities are temporarily very strongly exhibited and a control region in which the nonlinearities are hardly exhibited. A controller 1 which controls fuel pressure Pf of a fuel supply system 10 includes an ECU 2. The ECU 2 sets a target fuel pressure Pf_cmd, calculates a first control input Rsld for causing the fuel pressure Pf to converge to the target fuel pressure Pf_cmd, with equations (1) to (6), modulates the first control input Rsld with equations (11) to (31) to thereby calculate a second control input Udsm, and depending on whether or not during fuel-cut operation or pressure decreasing control, selects one of the first and second control inputs Rsld and Udsm as the control input Upf.
