Design and Application of Large Torque Electrical Load Simulator for Positive and Reverse Operation

摘要

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 realization principle of system is given according to the system index, and the stability and so on. The system mathematical model is established and the feedforward compensation method of torque and rudder angle is adopted to restrain the surplus torque according to the principle of invariance. So 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 the surplus torque and the system meets the high precision torque load under positive and reverse operation for rudder very well.
