摘要：

To solve the problem of acceleration performance degradation of aging engine, a model predictive control method with varying surge margin constraint is proposed. The acceleration process was divided into three stages according to the acceleration characteristics of the deteriorate engine, and different surge margin constraints were adopted at different acceleration stages. Considering that the model predictive control could handle constraints explicitly and adopt on-line receding horizon optimization to obtain the optimal control input, the model predictive control method was adopted in controller design. The alternating direction method of multipliers was used to solve the optimization problem for its high real-time performance. The acceleration performance recovery of the degraded engine was achieved. Digital simulation results show that the time consuming in acceleration is reduced by more than 35% compared with that of the degraded engine after using the acceleration performance recovery control method. © 2020, Editorial Department of Journal of Propulsion Technology.
