Embodiment 1
[0030] Such as figure 1 As shown, it is a schematic diagram of the air circuit of the air control and aerodynamic dynamic centering and deviation correction control method provided by the low-pressure signal control provided in Embodiment 1. The pneumatic control and pneumatic dynamic centering and deviation correction control method controlled by the low-pressure signal includes the following steps:
[0031] 1) The gas source is connected to the gas source signal generator to generate a low-pressure gas source signal 5, which is amplified by the pneumatic amplifier 6 to obtain a medium-pressure or high-pressure gas source signal;
[0032] 2) The air control valve 2 receives the medium pressure or high pressure air source signal to control the movement of the connecting rod 3 in the deviation correction cylinder 1;
[0033] 3) The connecting rod 3 moves in conjunction with the controlled object in the air source signal generator connected to the connecting rod.
[0034] The ...
