Diesel engine control method and device with feedback based on combination of LSTM algorithm and PID

The invention discloses a diesel engine control method and device with feedback based on combination of an LSTM algorithm and PID, relates to the technical field of diesel engine rotating speed control, and solves the technical problem of how to provide a diesel engine control method which can be applied to an initial state and is high in accuracy. Inputting the diesel engine parameters into an LSTM network for iterative training until a predicted rotating speed meeting a preset requirement is obtained; the difference between the predicted rotating speed meeting the preset requirement and the actual rotating speed at the previous moment is obtained and input into a PID network, and the optimal rotating speed is obtained; according to the method, the LSTM algorithm is adopted for prediction in the feedback link, the optimal rotating speed is obtained together with the PID control algorithm to control the diesel engine, the method can be applied to the diesel engine in the initial state, and high control effici
