Study of the Distributed Ground-Tunnel Pressure Measurement and Control Method

As the single ground environment and correction circuits of current pressure measurement and control system are too complicated to increase its test precision, the distributed ground - tunnel pressure measurement and control method is proposed.The paper focused on analyzing the idea of control strategy, describing the algorithm, principle, and other methods. Then main to deduce the relevant operations formula, give a detailed control block diagram. Finally, in order to detect the effect, the experimental test and simulation were carried out and then analyzing the results. Simulation is done to show the efficiency and feasibility of proposed approach.
