As a result of the radar system got interferenced or in the state of half silent  it can cause the guided precision drop badly In the modern electronic warfare  therefore it can lead to the equipment depended on electronic guidance cannot strike the incoming goals exactly. It will need to rely on optoelectronic devices to make up for its shortcomings  but when interference is in the process of radar leading  especially the electro-optical equipment is influenced by the roll  pitch and yaw rotation  it can affect the target appear outside of the field of optoelectronic devices for a long time  so the infrared optoelectronic equipment can not exert the superiority  and also it cannot get across weapon-control system "reverse bring" missile against incoming goals. So the conventional ship-borne infrared system unable to track the target of incoming quickly  the ability of optoelectronic rivalry declines heavily.Here we provide a brand new controlling algorithm for the semi-automatic searching and infrared tracking based on inertial navigation platform. Now it is applying well in our XX infrared optoelectronic searching and tracking system. The algorithm is mainly divided into two steps: The artificial mode turns into auto-searching when the deviation of guide exceeds the current scene under the course of leading for radar.When the threshold value of the image picked-up is satisfied by the contrast of the target in the searching scene  the speed computed by using the CA model Least Square Method feeds back to the speed loop. And then combine the infrared information to accomplish the closed-loop control of the infrared optoelectronic system tracking. The algorithm is verified via experiment. Target capturing distance is 22.3 kilometers on the great lead deviation by using the algorithm. But without using the algorithm the capturing distance declines 12 kilometers. The algorithm advances the ability of infrared optoelectronic rivalry and declines the target capturing time by using semi-automatic searching and reliable capturing-tracking  when the lead deviation of the radar is great. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

The flying qualities of aerocraft was directly effected by the autopilot  for the wide flight envelope aerocraft  on the basic of analyzing the typical trajectory  the three loop autopilots of roll stability  pitch and yaw were designed  using single-mode Transient suppression method  the overload due to control surface transition deflection was avoided when control parameters changing  the verification was done by non-linear simulation. The result showed that: Under the action of the disturbance torque  the maximum roll was less than 5  the range of the aerocraft was from 13.5km to 22.4km  the max height was about 5100m  the max deviation of lateral was about 42m  the maximum elevator deflection was less than 6.5 the control law was applicable within the effective range. An autopilot design method of wide flight envelope aerocraft was provided. 2011 IEEE.

In order to carries on the plan and the control to aircraft level flight  then obtain that the factors control the level route are the route position and the radius of turn  finally carries on the software simulation using this algorithm  the attitude and the route has been analyzed. First obtain that the factors control the level attitude are the roll angle and the yaw angle  and infers the algorithm of flight route  according to the attitude and the route restraint  and infers the computation algorithm of attitude  produce shortest aircraft level flight road map which through the giving route position on the software surface. According to this algorithm  it may control and plan the aircraft level flight  through to limit of the aircraft security attitude and the route position. 2010 IEEE.
