technical field [0001] The invention relates to the technical field of simulation test of electromechanical servo mechanism model flight, in particular to a method for real-time measurement of servo current when electromechanical servo mechanism model flight is loaded. Background technique [0002] In the hardware-in-the-loop simulation test of some control systems, the electromechanical servo system will participate in the test as an important single machine. Electromechanical servo includes servo control driver, servo power supply, servo mechanism and servo cable. [0003] The electromechanical servo mechanism model flight loading device is to simulate the load moment and the moment of inertia relative to the rudder shaft that the electromechanical servo will bear during real flight. According to the test requirements, the electromechanical servo should be installed in the real control cabin. [0004] In the past hardware-in-the-loop simulation test of electromechanical s...
