Abstract: PROBLEM TO BE SOLVED: To reduces vibrations and noise by inhibiting hunting in ISC control without causing engine stalling during idle operation of a flexible fuel internal combustion engine (for example, engine 1) capable of using alcohol-containing fuel.SOLUTION: A determination is made whether a first condition that a temperature state of an internal combustion engine is cold at a predetermined value or below and an alcohol concentration of fuel is higher than or equal to a predetermined value is satisfied and whether a second condition that indicates that a probability that the internal combustion engine stalls is lower than or equal to a predetermined level is satisfied (steps S5, S7). When both of the first and second conditions are satisfied, control over an intake amount is limited (step S8); whereas, when at least one of the first and second conditions is not satisfied, the limit is not applied (step S6).

Abstract: A control system which is capable of enhancing both the stability and the accuracy of control when the output of a controlled object is feedback-controlled by a plurality of control inputs. An ECU 2 of a control system 1 controls engine speed NE during idling by an ignition control input Usl_ig and an intake control input Usl_ar. The ECU 2 calculates a target engine speed NE_cmd according to an engine coolant temperature TW and the like (step 3), and determines the ignition control input Usl_ig and the intake control input Usl_ar with a plurality of predetermined target value filter-type two-degree-of-freedom sliding mode control algorithms [equations (1) to (12)] sharing one switching function à ne therebetween, such that the engine speed NE converges to the target engine speed NE_cmd (steps 4 to 7 and 9) .
