| Abstract: | The mechanical structure and operating principle of the control loading system of the Boeing 737-300 flight simulator was introduced, a mathematical model of the control loading system was founded and was expressed by means of block diagram. The characteristics of the extra force were studied. A method of position feedforward compensating the extra force based on the principle of structure invariance was presented. The result of the simulation shows theoretically that the feedforward compensating can reduce the interference caused by the extra force effectively. The feasibility and validity of the method were proved by experiments. |
