The invention discloses an electromechanical combined type constant force system control method based on model predictive control. The method comprises the following steps: S1, training set data acquisition; s2, establishing a kinetic model of the system based on a BP neural network; s3, inputting the data acquired in the step S1 into a dynamic model of the system to complete model training; and S4, designing a model prediction control controller, identifying the state of the electromechanical composite constant force system by using the model trained in the step S3, and calculating the optimal control force. According to the electromechanical combined type constant force system control method based on model predictive control, the constant force output precision and the response speed of the electromechanical combined type constant force spring support are improved, then high-precision vertical gravity compensation is achieved, and the trueness of spacecraft ground simulation is improved. 本发明公开了一种基于模型预测控制的机电
