Improving the Performance of an Actuator Control Scheme during Saturation

摘要: This paper first introduces a new control scheme for four fin missile actuation system. Exiting autopilot systems generally compute aileron, elevation, and rudder commands since these three variables dominantly influence the roll, pitch, yaw motion of vehicle. These are distributed to deflection controller actuates fins track defection command. The performance such schemes can be significantly degraded when actuators saturated due certain physical constraints, as voltage, current, or slew rate limit. analytically proves that proposed mitigates this problem, so it outperforms conventional in tracking if an actuator is saturated.Without any saturation, also proved equivalent scheme. Numerical simulations verify superiority theoretical analysis.
