Abstract: 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’t 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 .

Abstract: Simultaneity optimization for structure and weight distribution of neural network belongs to two class evolutionary method. First step, neural network structure is evolved; second step, neural network weight distribution is evolved, and use different code mode and fitness function in process of two class evolutionary, and modified genetic algorithm---reverse mutation operation was used. Reverse mutation operation can search according to the expectant direction, and do not bring premature convergence. Emulation result shows expectant optimization efficiency is obtained with genetic algorithm.

122火箭炮对称发射方法探讨文玉树

(国防科技大学 炮兵学院,湖南 长沙 410111)摘要:起始扰动是影响火箭炮射击密集度的主要原因之一。122毫米火箭炮引起起始扰动的主要原因是较大的闭锁

力产生回转力矩以及燃气流对定向器的冲击作用,故采用对称发射减小起始扰动。对称发射法是将离摇架中心较远的定向管一一对应同时发射,其应用会对火箭炮发射速度和密集度及作战效能带来重要影响。

Study on Symmetrical Launch Method of 122mm Rocket GunWEN Yu-shu

(College of Artillery, National University of Defence Technology, Changsha 410073, China)

Abstract: The initial disturbance is one of the main causes affecting the launch denseness of rocket gun. The slew moment generated by the lock force and the strike by the firing air current to the director is the main cause of the initial disturbance to 122mm rocket gun. It will reduce the initial disturbance by the symmetrical launch method in some degree. The method is that corresponding farside direction tube away to cradle center is launched at the same time. It will take important influence to the launch rate, the launch denseness and the campaign efficiency of rocket gun applying the symmetrical launch method.
