Roll Control of Course Correction Fuze for Dual-Spin Projectile with Fixed-Canards

In order to solve the input disturbance and model uncertainty problems of the roll channel of the course correction fuze (CCF) for dual-spin projectile with fixed-canards, a two-degree-of-freedom roll channel control method based on H_∞ loop shaping was proposed. Through the modeling of electrical and mechanical systems of the CCF, the calculation method of the electromagnetic control torque of the actuator was researched. Based on theoretical analysis and experimental test, the modeling method of the aerodynamic torque and the rolling damping torque of the CCF were studied, and then the roll channel control model was obtained. A two-degree-of-freedom roll channel controller based on H_∞ loop shaping was designed to control the roll angle of the CCF. Hardware-in-the-loop simulation experiments show that it is feasible to establish the roll channel control model by analyzing the electrical and mechanical systems of the CCF, and the designed roll channel controller can achieve accurate roll angle control.
