Abstract:A method for controlling the parabolic antenna using the macro fiber composite (MFC) is proposed in this paper.Firstly, the numerical simulation is used to evaluate the control characteristics of MFC.Secondly, the MFCs are glued on the surface of the paraboloid antenna specimen.The inverse piezoelectric effect of the MFC generates the deformation to drive the deformation of the parabolic antenna.The laser displacement sensor is used to monitor the displacement of the parabolic antenna in real time.Then, the feedforward compensation method is used to adjust the hysteresis in the MFC control.Finally, the simulation results are compared with the test results, and the requirements of the surface control accuracy of the parabolic antenna are obtained.
