ABSTRACT:
In an encoder unit for interpolating analog signals such as sine waves and triangular waves to obtain higher resolution or absolute values through A/D conversion and arithmetic processing, a delay time of data which is caused by A/D conversion and arithmetic processing time is eliminated to prevent deterioration of control performance. A storage unit for holding detected angular data and an output compensation unit for compensating the delay time are provided and a position change occurring during the delay time is predicted by the output compensation unit from angular data obtained from current and previous sampling cycles, and the delay time is compensated by adding the predicted position change to the current sampling data. Deterioration of the control performance can be prevented and inexpensive low-speed A/D converter and arithmetic processor can be used, and, therefore, required costs can be reduced.
