(1) 一、引言在系统中至少包括一个调制通道的随动系统,称为交流随动系统。由手交流随动系统使用的是体积小、重量轻、力矩惯量比大、机电时间常数小的空心杯子式两相伺服电机作为执行元件,所以动特性好,跟踪能力强。特别是它可用交流放大器放大,避开了直流放大器零漂的致命弱点,故在仪器仪表等小功率系统中广为采用。下面介绍的是红外型空-空导弹控制系统三维实时仿真中实现距离效应的一套交流随动系统。
(1) I. INTRODUCTION In the system at least one modulation channel servo system, known as AC servo system. By hand exchange servo system uses a small size, light weight, large moment of inertia, mechanical and electrical time constant small hollow-cup two-phase servo motor as the implementation of components, so good dynamic characteristics, tracking ability. In particular, it can be amplified with AC amplifier to avoid the fatal weakness of DC amplifier zero drift, it is widely used in low power systems such as instrumentation. The following is a set of AC servo system to realize the distance effect in the three-dimensional real-time simulation of infrared air-to-air missile control system.
