Abstract
A system for controlling an operating condition of an internal combustion engine includes a control mechanism responsive to a final control command to establish an engine control parameter, and a control computer configured to estimate a current value of the operating condition as a function of the final control command. The control computer determines an error value as a difference between an operating condition limit and the current value of the operating condition, and determines an operating condition parameter as function of the error value and of the current value of the operating condition. The control computer further determines a control command limit as a function of the operating condition parameter, and determines the final control command as a function of the control command limit and a default control command to thereby limit the operating condition to the operating condition limit.
