Research on the rolling channel control of micro tailless air-to-ground missile

Abstract

Due to the limitation of volume and weight, the missile body parameters of the micro tailless air-to-ground missile have a large range during flight, and the characteristics of the rolling channel are greatly different from those of conventional missiles, the stability control of the roll channel is greatly affected by the error of the actuator. Under the classic PID control, the HWIL simulation results show that the jitter of roll angle is obvious, and the anti-disturbance ability of the system is poor. Based on the classic PID, fuzzy control is introduced to optimize the design of rolling channel by using fuzzy online self-correcting PID control. The results of the hardware-in-the-loop simulation show that the jitter of roll angle is suppressed, which improves the characteristics of the roll channel and the control efficiency.
