Performance optimization research of PWARX model based on LSTM method

The PWARX model is a widely used modeling approach in hybrid systems. In this paper, a PWARX method based on LSTM is proposed. Firstly, the optimal control problem is clarified in the PWARX method. Secondly, the mechanism of PWARX based on the clustering method is described, and the LSTM algorithm is used to optimize the parameters and determine the region boundary conditions. Finally, the validity and reliability of the proposed method is verified by the engine universal characteristic curve, which solves the problem that the region boundary has gaps in the traditional method.
