摘　　要：针对固定翼二维修正引信在飞行控制过程中更新翼面滚转角时,现有的方法控制速度慢、工程实现复杂等问题,提出一种基于电流控制滚转角的PID控制算法。该算法将目标滚转角和实测滚转角的差值输入PID控制,根据力矩平衡关系推出角度变化量,输出控制电流,更新滚转角,形成闭环完成控制。简化了摩擦力矩计算方法,便于工程实现。仿真结果表明,该算法符合控制指标要求,具备一定抗干扰能力,满足固定翼二维修正控制需求。In view of the fixed-wing of the two-dimensional trajectory correction fuze,when the airfoil roll angle is updated during flight control.The existing methods,such as fuzzy control algorithm for slow control speed,dual closed-loop control algorithm,position speed dual loop PID algorithm,etc.,are complex in engineering implementation,therefore,a PID control algorithm based on current control roll angle was proposed.The algorithm input the difference between the target roll angle and the measured roll angle into PID control,the amount of change in angle was derived according to the torque balance relationship,then output control current,updated the roll angle,formed a closed loop to complete the control,which simplified the friction torque calculation method for easy engineering implementation.Simulation results showed that the algorithm met the control indicator requirements,and remained stable despite the introduction error,it had certain anti-interference ability and met the needs of the fixed-wing of the two-dimensional trajectory correction control requirements.
