摘要： A control system for a plant is disclosed. The control system includes a controller for controlling the plant based on a controlled object model which is obtained by modeling the plant. The controlled object model is modeled using an input and an output of the plant which are sampled at intervals of a sampling period which is longer than a control period of the controller. The sampled input of the plant is a filtered control output which is obtained by filtering an output of the controller. The controller carries out a control process of the plant at intervals of the control period.

摘要： A failure diagnosis apparatus for a throttle valve actuating device is disclosed. The throttle valve actuating device has an actuator for actuating a throttle valve provided in an intake system of an internal combustion engine and biasing elements for biasing the throttle valve to a predetermined retention opening. A feedback control of the throttle valve is performed so that an opening of the throttle valve coincides with a first predetermined opening. After the throttle valve is controlled to the first predetermined opening, a feedback control of the throttle valve is performed so that an opening of the throttle valve coincides with a second predetermined opening. It is determined that the throttle valve actuating device has failed when the time period during which the opening of the throttle valve remains in a predetermined determination range including the second predetermined opening, is shorter than a predetermined time period when performing the feedback control to the second predetermined opening.

摘要： An ignition timing control system for an internal combustion engine, which is capable of ensuring both stability of control in a steady operating condition of the engine, and an excellent follow-up property of a controlled variable to a target value in a transient operating condition of the engine, even when the controlled variable contains a lot of high-frequency noise components. In the ignition timing control system, a maximum pressure angle-calculating section calculates a maximum pressure angle based on an in-cylinder pressure and a crank angle position. A target angle-calculating section calculates a target angle. A maximum pressure angle controller calculates a maximum pressure angle correction term with a control algorithm to which is applied a sliding mode control algorithm, using a value obtained by performing ε-filtering on a switching function, such that the maximum pressure angle converges to the target angle. The ignition timing is calculated by adding corrected ignition timing to the value.

摘要： A control for determining a firing timing of an engine is provided. An in-cylinder pressure is detected at a predetermined time interval. An in-cylinder pressure for every predetermined crank angle is calculated based on the detected in-cylinder pressure. A motoring pressure in a case where combustion is not performed in the engine is estimated. It is detected that a pressure difference between the calculated in-cylinder pressure and the motoring pressure has exceeded a determination value. A time point is identified, as a firing timing, at which the pressure difference has exceeded a determination value with a finer resolution than the resolution of the predetermined crank angle interval through an interpolation calculation. The interpolation calculation uses a first crank angle when it is detected that the pressure difference has exceeded the determination value, the pressure difference corresponding to the first crank angle, a second crank angle previous to the first crank angle by the predetermined crank angle and a pressure difference corresponding to the second crank angle.

摘要： The natural vibration frequency of a roll resonance which does not occur since the engine rotation number is high in a normal operation range of an engine is detected at the time of engine start or stop when the engine rotation number is lower than the normal operation range, and thus the natural vibration frequency of the roil resonance can be detected with a good accuracy. A current is generated by an electromotive force of an actuator of the active vibration isolation support device excited by the engine immediately before stopping its rotation, and the frequency of the current is used to detect the natural vibration frequency of the engine, and the roll resonance of the engine is suppressed by controlling the operation of the active vibration isolation support device at the time of engine start based on the natural vibration frequency, thereby not only eliminating the need of a specific frequency detection sensor, but also effectively reducing the vibration at the time of engine start when the roll resonance becomes strong.
