解决好战车机动目标模型的动态辨识问题,对提高战车的战技性能及火控系统的进一步发展具有重要的意义。本文提出并设计了把自抗扰控制技术中的扩张状态观测器、跟踪微分器及最小二乘法结合起来用于研究机动目标的动态辨识问题。仿真结果表明,该方法具有速度快,精度好,能够满足实战要求的特点,有效地实现了机动目标动态辨识。

It is a significant thing to resolve the problem of dynamic identification of chariot maneuvering target ,which can increase the capability of the chariot in the battle and promote the development of the firepower control system. In this paper, the method of combining expand state observer, track differentiator with least square algorithm related to the active disturbance rejection control technique is brought out and designed . It can be used to study the problem of dynamic identification of maneuvering target. Simulation results indicate that the method can satisfy the demand of actual combat in the respect of speediness and accuracy and be effective in realizing the dynamic identification of maneuvering target.
