Simulation Results

Aiming at the superfluous force existing in the electric load simulator which can influence the load precision, the text researches the method to improve the control performance of the load system. The work principle of the electric load simulator was introduced, and building the control model of the load system based on, the whole electric load simulator control model was built. It designs feed forward compensation control algorithm. The simulation results proved that the method can solve the interference problem caused by superfluous force in theoretically.

Rudder Angle

In order to meet the testing requirement of positive and reverse operation large torque load for new rudder, an electrical load simulator is designed. The system mathematical model is established and the feedforward compensation control of torque and rudder angle is adopted to restrain the surplus torque according to the principle of invariance. The high precision large torque load under positive and reverse operation for rudder is realized by torque and position hybrid control. The practical application shows that the proposed method can effectively restrain surplus torque and the system meets the high precision torque load under positive and reverse operation for rudder very well.
