Radar Servo System Design Based on Brushless DC Motor
Author(s): 
Pages: 479-484
Year: Issue:  6
Journal: Radar Science and Technology

Keyword:  无刷直流电机雷达伺服系统仿真轴角数字变换器;
Abstract: 介绍了连续扫描工作的长寿命伺服系统设计与实现,选用无刷电机作为执行元件并选用无刷旋转变压器作为测角反馈元件来实现长寿命要求.文中描述了直流无刷电机的Matlab模型和基于无刷电机的雷达伺服系统仿真模型.伺服系统的校正运算通过PI调节器实现,参数通过系统仿真决定,简化了系统参数的设计.仿真模型中考虑了结构谐振,用以保证调节器的可实现性.功放电路由单路PWM经FPGA分离出6路开关信号来控制,简单可靠...
