To evaluate the performance of the angle demodulation algorithm for servo sensor, the high precision signal simulator for servo sensor that can provide true value of information for angular position and angular speed of the rotor is designed. The simulator can emulate the output signals of magnetic encoder, rotary transformer (resolver), and incremental optical encoder. To reduce the quantization error of the system, DSP28335 is used as the CPU and DAC7664 is used for D/A conversion. The error analysis indicates that the signal simulator designed for servo sensor features high precision. The experimental results verify the accurateness of error analysis; that means the simulator designed possesses certain practical value.
