Abstract: In a temperature control system of a plant such as an engine exhaust system, there are provided a catalyst heat model calculating a temperature estimated value of the plant, a temperature sensor model inputting the calculated value to calculate an output estimated value of a temperature sensor, a temperature controller controlling the plant temperature based on the estimated value, and a model parameter corrector correcting the plant model parameter so as to minimize error between the temperature sensor output and the calculated output estimated value. With this, even in the case where the temperature sensor has a large response lag, the temperature estimated value can nevertheless be corrected with high accuracy, without, for example, causing severe overshooting.

Abstract: A method of controlling ignition timing of an engine. In the control method, final ignition timing for performing ignition is calculated by adding a variation component to a set ignition timing. According to the final ignition timing, an indicated average effective pressure of an in-cylinder pressure detected when ignition is performed is calculated. An ignition timing characteristic curve indicating the correlation between the indicated average effective pressure and the variation component is estimated and optimal ignition timing is calculated from the characteristic curve. Feedback control for converging the set ignition timing to the optimal ignition timing is then performed. Consequently, the ignition timing is controlled to an optimal ignition timing corresponding to a current operational state of the engine.

Abstract: A transmission comprises a first transmission mechanism and a second transmission mechanism. When a clutch is in an engaged state, the first transmission mechanism transmits a driving force from the engine to the axle shaft. When a clutch is in a disengaged state, the second transmission mechanism transmits a driving force from the engine to the axle shaft. An electromagnetic brake is connected to the second transmission mechanism. A braking force generated by the electromagnetic brake allows the transmission of a driving force by the second transmission mechanism. Thus, a driving force is continuously provided even when the clutch is released for a gear change operation.

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 for a contact mechanism for preventing a lack of a pressing force applied from a contacting member to a contacted member when determining a control input to an actuator moving the contacting member by a position control. The controller sets a target position of the contacting member, grasps an actual position of the contacting member, determines a control input to the actuator (so as to increase an output of the actuator along with an increase in a difference between the target position and the actual position of the contacting member to eliminate the difference), and detects that the contacting member contacts the contacted member.

Abstract: A controller for a plant that can compensate for non-linear property and reduce oscillation of output of a controlled object even when the controlled object has high non-linear property is provided. The present invention provides a controller for a plant that uses PWM algorithm. The device calculates provisional control input for controlling output of the plant at a target value, and divides the provisional control input into a plurality of components. The controller PWM-modulates at least one of the plurality of components, and sums the PWM-modulated component and other components to produce a control input to the plant. The controller minimizes variations in input while maintaining the ability of PWM modulation to compensate for non-linear property of the plant.

Abstract: A control system which is capable of compensating for and suppressing the influence of a periodic disturbance on a controlled object more quickly, even when the controlled object is subjected to the periodic disturbance the amplitude of which periodically changes, thereby enhancing the stability and the accuracy of control. The control system includes an ECU. The ECU calculates disturbance compensation values for compensating for a periodic disturbance by searching maps and tables, in timing of generation of each pulse of a CRK signal. The ECU calculates control inputs at a predetermined control period, with predetermined control algorithms, according to the disturbance compensation values read in at the control period, respectively.
