随动系统设计与仿真分析

Design and Simulation Analysis of Servo System

自行高炮随动系统具有系统加速度大、负载惯量大、快速反应时间短的特点,为此,在设计中建立了系统的动态数学模型,采用频率特性法与MATLAB仿真设计手段相结合的方法,设计了系统校正环节,使系统具备很好的跟踪精度和快速反应能力,并具有较强的鲁棒性。经系统试验台架、火炮射击试验考核,各项指标满足要求,达到了动态设计的目的。

The servo system of self-propelled antiaircraft gun has the characteristics of high acceleration,large inertia of load and the rapid reaction time,so the method of frequency characteristic and Matlab simulation are combined to establish the dynamic mathematics model in which the correction loop is designed to achieve fine tracing accuracy,rapid reaction time and strong robustness. The method has been tested through experimentations on the bracket and gun firing.
