An angle mechanism control system

taking SCM as a core

in the low speed pressurized wind tunnel model support system is introduced. This system uses the interface circuit of SCM to realize the control of the servomotor and the communication and data transfer among the master computers and to solve the problems of the unaccuracy caused by the mechanical backlash and of the model control caused by the nonlinear movement of the angle mechanism bearing rod in the model support system. The military control precision required by the wind tunnel test is achieved.
