Trajectory control algorithm is also presented to make the excursion of flight converge to zero in given limited time during flying . it is mainly used to control and reduce the excursion and crab angle within given limited time when the aerocraft is following the reference flight path 然后本文提出了用于控制飛行器在跟蹤參考航跡過程中出現(xiàn)的航跡偏移和偏航角的航跡控制算法,該算法能有效地使航跡偏移量和偏航角在給定的時間約束內(nèi)收斂。
After introduced its task and construct of the controller of the homing gliding missile , the longitudinal and lateral motion equations are provided . a continuous fuzzy - pid control system combined the advantages of fuzzy control and pid control is presented , and could be guaranteed the stability of the system using popov stability criterion . the results of simulation show that the fuzzy - pid control is able to provide a better relative stability and robustness , also have better dynamic and static characteristics than the pure pid control 將模糊控制和pid控制相結(jié)合,研究了一種基于模糊pid的連續(xù)控制器,利用波波夫穩(wěn)定判據(jù)判定該控制器是漸進穩(wěn)定的,并將其應(yīng)用于制導(dǎo)滑翔彈俯仰角、偏航角、滾轉(zhuǎn)角穩(wěn)定回路中,設(shè)計仿真結(jié)果表明,該種連續(xù)控制器可使系統(tǒng)獲得很好的穩(wěn)定性和魯棒性,動、靜態(tài)性能比單純pid控制都有較大提高。
