Description
Summary:In order to solve the underdamping problem for a rolling missile, at first, design the lateral acceleration autopilot; secondly, study the projection of control command and control strategy called pulse width modulation (PWM) of command in engineering, then design the damping loop for this rolling missile and simulate the control system while inputting step signal. The digital simulation results indicate that autopilot can improve characteristics of the missile. Moreover, a Three-axis turntable is employed to simulate attitude of the missile. A Two-axis MEMS gyro is fit on the simulation facility at a specific installation which solves the projection of command, and then a Hardware-in-the-Loop test is taken to inspect damping loop while pitch channel is disturbed by low-frequency noise. The results of the test indicate that with damping loop it is effective to improve characteristics and enhance the ability of suppressing noise.
