直流伺服系统转速和转矩参数的辨识

Identification of Velocity and Torque Parameters in DC Servo-system

在双闭环直流伺服系统中，需要传感器检测电流和转速的反馈值。运用状态观测器理论，设计出一种能够估计转速和负载转矩参数的二维观测器，从而简化了电路，通过软件仿真，达到了设计要求。

A sensor, detecting the feedback value of current and revolution, is needed in double closed DC servo-system. Using state observer theory, a two dimensions observer that can be used to estimate the parameters of velocity and load torque, is designed and the corresponding circuit is simplified. The computer simulation results correspond to the design requirements.
