Research on large flow intelligent liquid supply system in fully mechanized working face
Gong-kuang zidonghua, 2022 The liquid supply system in fully mechanized working face has the problems of insufficient liquid supply capacity, large pressure fluctuation and poor system operation stability. In order to solve the above problems, an immune particle swarm optimization fuzzy neural network PID (IPSO-FNN-PID) algorithm is proposed.
