| Abstract: | Meeting the needs of data read in servo control system to read the absolute encoder data based on the Biss protocol, two aspects of hardware circuit design and software design are studied and a scheme is designed.System hardware system consists of power supply protection, differential signal of interface and Biss master controller.Firstly, the hardware circuit, for the encoder data reading, is designed.Secondly, A finite sate mechanism is programmed through FPGA, which is based on the Biss protocol.Finally, the design is verified by experiment,providing a certain reference for the high-precision encoder based on Biss agreement in the application of servo control system. |
