Abstract:
The design of the torque loading system of stepper motor for liquid oxygen and kerosene engine is introduced in this paper.The structure,hardware and software design of the motor torque loading system taking magnetic powder brake as the loading core are described.The fuzzy PI control algorithm of the torque loading system is elaborated.The fuzzification and de-blurred processing of the PI control parameters are performed.The fuzzy inference rule is drawn up.The dynamical adjustment of PI control parameters for the torque loading system was achieved.The loading accuracy of the stepping motor torque loading system was improved.The practical application proves that the developed motor torque loading system can realize the simulation loading and parameter measurement of the motor used in LOX/kerosene engine and meet the testing requirements of the motor.
