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 ECUof a control systemcontrols engine speed NE during idling by an ignition control input Usl_ig and an intake control input Usl_ar. The ECUcalculates a target engine speed NE_cmd according to an engine coolant temperature TW and the like (step), 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 σne therebetween, such that the engine speed NE converges to the target engine speed NE_cmd (stepstoand).
