一、前言本文讨论的是AIM-7E(麻雀Ⅲ_B)空空导弹液压舵机的数学模型。 AIM-7E舵机为一角位置返馈液压动力系统,是制导系统中一个重要执行部件。研究控制系统时,人们习惯于把它视作位置输出的一阶惯性环节,而忽视了负载力矩返馈对液压系统的影响。实际上,这种液压舵机的动态特性与一阶惯性环节会有较大差异,并且影响导弹的
I. Preface This article discusses the mathematical model of AIM-7E (Sparrow III_B) air-to-air missile hydraulic steering gear. AIM-7E steering gear for the corner position feedback hydraulic power system, is an important guidance system components. When studying the control system, people are accustomed to regard it as the first-order inertia of the position output, ignoring the influence of the load torque feedback on the hydraulic system. In fact, the dynamic characteristics of this hydraulic servo and first-order inertia will have a greater difference, and affect the missile’s
