Abstract :
The sensor for detecting the feedback value of current and speed is needed in a double closed DC servo system. A two dimensional observer that can estimate the value of speed and load torque is designed. Using the state observer theory, an estimated value is used in the DC servo system, and the load torque achieves interference compensation. The simulation results achieved the designed requirements
