Multirole target must horizontally fly over large air area.Based on the research object,the random radiation optimization of multitargets and multi-restrictions is introduced into the design of altitude control system.Under the condition that restrictions are given,azimuth angle stability loop and altitude stability loop control parameters,the size of various program command signal and working time are chosen reasonably so as to minimize the lifting time of target,and overshoot approximate to zero.All trajectory simulation results show that the designed altitude control system can achieve the object of flight over large airspace by the proposed method.
