【Abstract】 To resolve the inadaptability of an anti-tank missile in its application on high plateaus, the missile’s characteristics in frequency domain and control system parameters were analysed and the characteristics of the missile used on high plateaus were studied. Non-linear control method was introduced in the modification design of pitch and yaw channel parameters of the guidance loop. The design was validated by numerical simulation. The results showed that the stability of the guided system on high plateaus could be improved effectively using the non-linear control method. The performances of the modified missile satisfied the requirements when used on high plateaus.更多还原
