伺服系统中模糊控制器的设计与仿真

同步随动系统是雷达系统中十分重要的单元，它驱动平面位置显示器的偏转线圈跟随雷达天线同步转动，以便精确地测量目标方位，是典型的角度伺服系统。在现行装备中，该系统大多采用模拟调节器，带来了参数调节不方便、动态特性差和跟踪精度低等缺点，因此采用现代控制理论对其进行改造十分必要。根据交流电机的数学模型，对雷达同步随动系统采取了数字PID和模糊控制两种控制策略，通过仿真分析，说明了采用模糊控制的先进性。

Fuzzy Controller Design and Simulation for Servo System

The synchronous subsystem is the important unit in radar system. It moves the bias coil of plane position indicator to rotate synchronously with radar antenna in order to measure the target position precisely. It is the typical position servo system. In actual equipment, this system adopts the analogue adjustor which results in a series of disadvantages such as inconvenient parameter adjusting, poor dynamic character low following accuracy. So it is necessary to rebuild the used system using modern control theories. Based on the model of alternate motor, this paper applies digital PID and fuzzy control strategies on radar synchronous system and discusses the advantages of the later through simulation analysis.
