Other AbstractBased on the comprehensive performance specifications of simulator of fire control system in an armed helicopter,a novel debugging strategy is proposed in this paper.On the basis of the deduction of mathematic model of simulator,four close-loop control scheme was adopted in the whole control system ,which consists of current feedback loop,velocity feedback loop,modulated position feedback loop and digital position feedback loop.The feedback signals of tachometer and potentiometer should be calibrated before debugging the testing simulator.Cascade phase advance-lag corrective network was adopted in the forward channel of internal loop.24 bits complementary code was adopted in the digital position feedback signal format of roll frame,pitch frame and yaw frame,and the three-point digital differential analyzer algorithm was adopted in the digital velocity calculation.On the basis of digital frequency discrimination of feedback signals,the digital position feedback loop was debugged with variable frequency feed forward compensation.Series hardware2in2the2loop experiments have been conducted in the past year. Experiment results demonstrate that this simulator of fire control system in an armed helicopter has very small amplitude error,phase error and wide frequency response ,which can satisfy the static and dynamic performance specifications very well.
