    Abstract: A control system for a plant is provided. This control system can control the plant more stably, when the model parameters of the controlled object model which are obtained by modeling the plant, which is a controlled object, are identified and the sliding mode control is performed using the identified model parameters. The model parameter identifier (22) calculates a model parameter vector (θ) by adding an updating vector (dθ) to a reference vector (θbase) of the model parameter. The updating vector (dθ) is corrected by multiplying a past value of at least one element of the updating vector by a predetermined value which is greater than “0” and less than “1”. The model parameter vector (θ) is calculated by adding the corrected updating vector (dθ) to the reference vector (θbase).

    Abstract: A control system for a plant, having an identifier and a controller. The identifier identifies model parameters of a controlled object model which is obtained by modeling the plant. The controller calculates a control input to the plant so that an output from the plant coincides with a control target value, using the identified model parameters. The controller calculates a self-tuning control input, using the model parameters identified by the identifier. The controller further calculates a damping control input according to the rate of change in the output from the plant or the rate of change in a deviation between the output from the plant and the control target value. The controller calculates the control input to the plant as a sum of the self-tuning control input and the damping control input.

    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.
