摘要： The temperature of an exhaust gas flowing through an exhaust passage 3 is estimated or detected, and the temperature of an active element of an exhaust gas sensor 8. (O2 sensor) is controlled at a predetermined target temperature by a heater using the estimated or detected temperature of the exhaust gas. For estimating the temperature of the exhaust gas in the vicinity of the exhaust gas sensor 8, the exhaust passage 3 extending up to the exhaust gas sensor 8 is divided into a plurality of partial exhaust passageways 3a through 3d, the temperatures of the exhaust gas in the partial exhaust passageways 3a through 3d are estimated successively from an exhaust port 2 of an engine 1. The temperature of the exhaust gas is estimated according to an algorithm which takes into account a heat transfer between the exhaust gas and passage-defining members 6a, 6b, 7 which define the exhaust passage 3 and a heat radiation from the passage-defining members into the atmosphere. A control input that is applied to the heater includes at least a component depending on the temperature of the active element of the exhaust gas sensor 8 and a component depending on the temperature of the exhaust gas. Even if the temperature of the exhaust gas changes, the temperature of the active element of the exhaust gas sensor 8 can be controlled stably at the desired temperature.

摘要： 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.

摘要： A control device for controlling an engine, comprising a variable lift mechanism capable of changing the lift of a valve and a variable compression ratio mechanism capable of changing a compression ratio in a combustion chamber. The control devise controls the variable lift mechanisms and the variable compression ratio mechanism so that, when a requested engine output is increased, a compression ratio decreasing rate is increased over a lift increasing rate and, when the requested engine output is reduced, a lift decreasing rate is increased over a compression ratio increasing rate. When the engine comprises a variable phase mechanism capable of changing the phase of the valve, the control devise controls the variable compression ratio mechanism and the variable phase mechanism so that, when the requested engine output is increased, the compression ratio decreasing rate is increased over the change rate of the phase to a delay angle and, when the requested engine output is reduced, the change rate of the phase to an advance angle is increased over the compression ratio increasing rate. Thus, the contact of the valve with a piston can be avoided.
