Abstract: In the calibration of the rocket thrust measurement the key is controlling the loading process.A high calibration accuracy is needed and there is variable speed disturbance of parameter change and hysteresis change in the calibration.A fuzzy control method applied to control the loading for the calibration accurately and automatically is presented and researched.A builp up method was proposed and applied to establish a 4 dimensional fuzzy control model to eliminate the disturbance and the hysteresis. And the principle of the fuzzy control is discussed in detail. The application of the control method is analysised. The conclusion is that the control method and the model are satisfactory and effective in the calibration.
