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 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 (d θ) to a reference vector (θ base) of the model parameter. The updating vector (d θ) 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 (d θ) to the reference vector (θ base).

摘要： An object system is regarded as being equivalent to a system for generating an output of an O2 sensor or exhaust gas sensor from a target combined air-fuel ratio that is produced by combining target air-fuel ratios KCMD for respective cylinder groups according to a filtering process of the mixed model type. With the equivalent system as an object to be controlled, an air-fuel ratio processing controller determines a target combined air-fuel ratio, and determines a target air-fuel ratio KCMD for each of the cylinder groups from the target combined air-fuel ratio. The air-fuel ratios in the cylinder groups are manipulated into the target air-fuel ratio according to a feed-forward control process.
