Control apparatus for internal combustion engine

摘要

A control apparatus for internal combustion engine using a mathematical model comprises integrating means for integrating a deviation obtained by subtracting a control result value from a control object value, and control value control means that controls the control value based on an integration value from the integrating means and quantity of state obtained from the mathematical model, wherein the integrating means interrupts integration of the deviation if the control value is an upper limit value and above or a lower limit value and below and if the control object value changes while the integration is interrupted and the deviation turns to a negative value while the control value is kept the upper limit value and above or the deviation turns to a positive value while the control value is kept the lower limit value and below, the integration is restarted from an integration value at the time of the interruption.
