Aero-engine direct thrust control with nonlinear model predictive control based on linearized deep neural network predictor

Abstract: A novel nonlinear model predictive control method for aero-engine direct thrust control is proposed to improve engine response ability and reduce computational complexity of nonlinear model predictive control. The control objective of the proposed method is the thrust directly instead of the measurable parameters. The linearized model based on online sliding window deep neural network is proposed as predictive model. The online sliding window deep neural network has strong fitting capacity for nonlinear object… Show more

“…In this study, the MPC controller was designed to identify the engine control modes, which was achieved by using Lagrangian multipliers to handle the constraint inequalities and Hildreth's quadratic programming to select the controller weighting values [103]. To improve the engine response performance and reduce the computational complexity, direct thrust control with nonlinear MPC was proposed based on a linearized online sliding-window deep neural network predictor [104]. For application in EAP systems, a coordinated MPC controller has been developed to achieve the setpoint tracking of large transient thrust and electrical loads whilst ensuring system constraints [56,105].…”

“…Experiments show that a three-layer BP neural network can complete a mapping from any n-dimensional input layer to m-dimensional output layer. [28][29][30] This paper adopts a three-layer BP neural network model, as shown in Figure 5, w ih and w hj are the weights between layers, and q is the bias.…”

“…The MPC controller choses the optimal control law in addition to the prediction of next control in advance. [19][20][21] The entire analytical model of the power rectifier and its future performance are considered while controlling the active powers and reactive powers. Therefore, it is a promising solution and popular strategy for the power converters because of having many benefits, such as lack of modulator, fast dynamic response, and the controller flexibility in terms of system requirements.…”
