[Abstract]:The underground drainage system of coal mine is a multi-input and multi-output system. The control of such complex system has become the key problem to be solved urgently in the process control. It also plays an important role in improving the safety of coal mine production. This paper studies the control method of multivariable nonlinear system based on underground drainage system of coal mine, and carries on the corresponding control to the underground drainage system of coal mine. Based on the theoretical model of underground drainage, the simulation system of underground drainage is designed, and the accuracy and feasibility of the corresponding control methods are analyzed. A comprehensive analysis of underground drainage system in coal mine enterprises is carried out. A multivariable nonlinear downhole drainage control method based on neural network is proposed. The related control is given when the model of underground drainage system in coal mine is unknown. Methods. Neural network is used to compensate for the influence of nonlinear term on underground drainage closed loop system in coal mine. Multi-model switching is used to deal with the influence of dynamic characteristics of underground drainage system. A neural network-based PID control method is presented by using PID algorithm. When the parameters of the control object of the underground drainage system are unknown, Combining the correlation adaptive algorithm with the nonlinear PID algorithm, a new control algorithm is proposed, and the validity of the proposed method is verified. In this paper, the control method of multivariable nonlinear system based on underground drainage system in coal mine is studied. Through the simulation experiment on the complex industrial process of underground drainage in coal mine enterprises, it is proved that the control method proposed in this paper is effective and realizable.
