    Abstract: A control for avoiding interference between a valve and a piston of an engine is provided. The engine has a variable lift mechanism that is capable of changing a lift amount of the valve and a variable phase mechanism that is capable of changing a phase of the valve. A predicted value of the phase is calculated. A first determination of whether or not the predicted value has exceeded a first predetermined value is made. If it is determined that the predicted value has exceeded the first predetermined value, at least one of the lift amount and the phase is changed to avoid the interference between the valve and the piston. By using the predicted value, the interference can be avoided without delay.

    Abstract: An actuator control system restrains hindrance to an object under control by an interfering substance that exists on its traveling path when the object is moved toward a target position on one axis while the object has been positioned at a target position on the other axis. A selection controller sets a switching function setting parameter (VPOLE_sl) so that a disturbance suppressing capability level is lower at a set value (VPOLE_sl_l) at time (t31˜) when a shift arm is moved in a shifting direction by a shift controller than at a set value (VPOLE_sl_h) at time (˜t31) when the shift arm is moved in a selecting direction to be set at a certain gearshift position (|VPOLE_sl_h|

    Abstract: To provide a control system for an internal combustion engine, which is capable of attaining both the securing of excellent drivability and the reduction of impact occurring when a movable part abuts against a restriction part at the same time. The control system 1 includes a variable valve lift mechanism 50 that changes a valve lift Liftin, and includes a restriction part 67a for having a movable part 65 abut thereagainst for restricting the valve lift Liftin such that it does not exceed a predetermined limit lift Liftin_L, and a variable intake air amount mechanism 11 that changes the intake air amount. The control system calculates a control input ULiftin for control of the variable valve lift mechanism 50, with a predetermined control algorithm including a disturbance suppression parameter POLE_lf (step 54), such that the valve lift Liftin follows up the target valve lift Liftin_cmd. When a determination that the movable part 65 has abutted against the restriction part 67a is made, the control system sets the disturbance suppression parameter POLE_lf such that the degree of suppression of the disturbance thereby becomes smaller than before the determination (step 73).

    Abstract: There is provided a control method for sufficiently compensating the non-linear characteristic for a plant having a strong non-linear characteristic and satisfying the follow-up and stability for a plant having a large control amount fluctuation. There is provided a plant control device using modulation algorithm. The control device includes: means for calculating a temporary control input for controlling the plant output to a target value; means for dividing the temporary control input into a plurality of components; means for modulating at least one of the components; and means for adding the modulated component to another component so as to generate a control input. Thus, it is possible to minimize the input fluctuation caused by modulation while maintaining the compensation ability of the non-linear characteristic such as plant friction and hysteresis attributed to the conventional modulation algorithm. Accordingly, even in a plant in which the temporary control input is greatly changed, it is possible to prevent oscillation of the output, thereby improving the controllability.

    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 transmission control system is capable of maintaining good positioning performance even if a dynamic characteristic of a transmission is out of a predicted range. A sliding mode controller provided in a shift controller is a controller having two degrees of freedom that makes it possible to independently specify a follow-up characteristic of an actual position of a shift arm to follow a target position in a shifting direction and a disturbance suppressing characteristic respectively. The sliding mode controller determines a control input to be supplied to a shift motor of a shifting device. A sliding mode controller provided in a selection controller is a controller having two degrees of freedom that makes it possible to independently specify a follow-up characteristic of an actual position of a shift arm to follow a target position in a selecting direction and a disturbance suppressing characteristic, respectively. This sliding mode controller determines a control input to be supplied to a selection motor of a selecting device.
