Terahertz wave transmitting and receiving double-arm linkage control system

The invention discloses a Terahertz wave transmitting and receiving double-arm linkage control system, which comprises a Terahertz wave transmitting arm, a Terahertz wave receiving arm, a voltage power supply module, a single chip microcomputer main control module, a stepping motor driving module, a stepping motor execution module, a linear magnetic encoder feedback module and a tail end grating detection module. The regulation and control process is different from a traditional method of mechanically regulating and controlling terahertz wave receiving and transmitting arms, an electric control method is adopted, two stepping motors are used for controlling the transmitting arm and the receiving arm respectively, and two closed-loop feedback controls are adopted to realize stable control, precision control and error regulation of the motion process of the transmitting arm and the receiving arm; the two closed-loop feedback controls are respectively angle precision and error detection feedback in a rotation pr
