Steering Gear System Controller In Missile Based On Adaptive Fuzzy PID Algorithm

In this paper, aiming at the steering gear machinery in some missiles,adopting the combined configuration of small rare earth torque motor and harmonic drive reducer, a adaptive fuzzy strategy is designed. Considering the change with velocity and small damp of harmonic drive, adopting the characteristic of many methods of control, learn from other's strong points to offset one's weakness, the adaptive fuzzy PID control system is used here. At the same tine, a project which using infinite impulse response filter is put forward to improve the capability and remove noise.In the aspect of hardware system, the DSP control system with CAN2.0 and based on TMS320F2812 has been designed, which is more dependable. The testing result indicates that this control system has the merits such as good capability of anti-jamming, excellent control quality, and so on.At the end of the paper, all factors that affect system performance are analyzed, and optimization designs are presented.
