This paper proposes a novel adaptive backstepping control for an innovative engine cooling system. The engine cooling system belongs to a special class of nonlinear systems with both matched and mismatched state-dependent lumped disturbances. The parameter update laws resemble a nonlinear reduced-order disturbance observer and guarantee the convergence of the estimated parameter values to the true...
In this paper, a robust nonlinear control approach based on a simplified control-oriented model of an engine cooling system for vehicles is presented. An electrically driven radiator fan is considered as a control input. Based on the system description, a second-order sliding mode control is proposed to track desired trajectories of the engine outlet temperature. The second-order sliding mode control...
In this paper, a robust nonlinear control approach based on a control-oriented model of an engine cooling system for vehicles is presented. The angular velocity of an electrically driven radiator fan is considered as the control input to adjust the cooling heat flow corresponding to a desired engine cooling performance. For smooth control actions and an avoidance of chattering, a dynamic sliding mode...
In this paper, a nonlinear control-oriented model of the thermal behaviour of an engine cooling system for vehicles is presented. The volume flow of an electrically driven coolant pump and the angular velocity of a radiator-fan unit serve as control inputs in a flatness-based nonlinear control approach. A constrained control problem arises due to the given physical bounds on the actuator inputs. Based...
