“…For single-stage turbocharging devices, a variety of control concepts have been developed. The control techniques were applied in various set-ups for single-stage turbocharged diesel engines [6][7][8][9][10], as well as for different gasoline engine set-ups [11][12][13][14][15]. In the case of two-stage turbocharging, less research has been conducted so far.…”

Increasingly complex air path concepts are investigated to achieve a substantial reduction in fuel consumption while improving the vehicle dynamics. One promising technology is the two-stage turbocharging for gasoline engines, where a high pressure and a low pressure turbocharger are placed in series. For exploiting the high potential, a control concept has to be developed that allows for coordinated management of the two turbocharger stages. In this paper, the control strategy is investigated. Therefore, the effect of the actuated values on transient response and pumping losses is analyzed. Based on these findings, an optimization-based control algorithm is developed that allows taking both requirements into account. The developed new controller allows achieving a fast transient response, while at the same time reducing pumping losses in stationary operation.

“…In this paper, we utilize fuzzy PID control method to meet the torque demand. The turbocharged engine has been considered as a quite complicated and nonlinear system with strong coupling [9], which results in an increase in difficulty and complexity of control design. It has been proved that the fuzzy PID control can yield a good control performance for this system [10].…”

This paper focuses on the modeling and control of a turbocharged gasoline engine air path system. Firstly, based on mean value modeling theory, a turbocharged engine air path model is developed according to its structure characteristics and actual working process. Secondly, aiming to achieve the desired engine torque, the desired engine torque is transformed into the corresponding intake manifold pressure via maps. Thirdly, based on fuzzy PID control algorithm, the throttle and wastegate controllers are designed to track the intake manifold pressure, and then the torque demand can be satisfied through the throttle and wastegate control. Finally, the effectiveness of the proposed control system is verified and the control performance is presented by the experimental results.

“…In [9], a control strategy based on switching fuzzy model is proposed to control intake manifold pressure. In [10,11], model predictive control algorithm is used to control turbocharged engine. However, according to the characteristics of the practical application, drivers are more concerned about the engine output torque, and hence it is more reasonable to utilize the engine output torque as the control objective.…”

Turbocharging technology has been widely used in automotive products for improving the power of the vehicle effectively. In this paper, a physics-map mixed air path model of turbo-gasoline engine is proposed. The accuracy of the proposed model is validated by the engine dynamics simulation software enDYNA. Then, an air path control system which contains torque based throttle control and intake manifold pressure control is deduced to coordinate the throttle and wastegate for satisfying the torque demand and the limitation of intake manifold pressure. And a control strategy is proposed in order to fully utilize turbocharger. Finally, the simulation results show the effectiveness of the control system.
