The reason of the error in axle-angle positioncoder for precision tracking and instrumentation radar is analyzed in this paper, and the concrete measures of controlling the error are also proposed.
The inaccurate measurement of initial position of motor rotor when the motor starts is a problem existing in a servo system applying increment photo-electricity pulse coder.
