摘要
某型防空导弹采用改进的数字分时段积分分离PID控制。根据目标和导弹偏差及其变化控制积分系数,若比例项、积分项和微分项符号相同而偏差较大时积分项不工作,其符号不同时积分项工作。仿真表明此控制方法对于机动目标能够使偏差的振幅减小,提高命中率。
Improved digital time-segmented PID control separated by integral action coefficient was adopted in antiaircraft missile. Integral coefficient was controlled according to windage and change of target and missile. The integral item doesn抰 work when the signs of proportion, difference and integration are the same and the value of deviation is very large. If the signs are different, integral item works. The result of simulation shows that the amplitude of deviation can be reduced with the method, and improve the hit rate.
