Detection of Rotor Position Angle(PA) and Speed in Double-Fed Generator 双馈发电机转子位置角(PA)及转速的检测
Through the solution, the star position angle can be found with so-called " star distance "( Short for the spherical distance between two stars ) determined So as to have the fix solved. 用解球面三角形的方法,通过两天体的球面距离,求得星位角,从而求得船位的经纬度。
A new closed-loop instantaneous speed observer is designed using rotor position angle observation error as feedback variables. 本文以电机转子位置角(PA)度观测误差为反馈变量,设计了一种新型的闭环瞬时速度观测器,通过增加位置反馈闭环提高了速度观测器的抗扰性能。
And when the motor starting, the precision requirements for the rotor initial position angle is lower. 且在电动机起动时,对转子初始位置角(PA)的精度要求较低。
By analyzing and disposing the output signal of the signal generator and the position angle signal of the servo system, the software of monitor testing can draw command curve, take-over curve and error curve. 监控测试软件获得信号发生器的输出信号和伺服系统的位置角(PA)信号并对两种信号进行分析处理,可以绘出指令曲线、接收曲线和误差曲线;
