Configurable and Modular Development of Multi-Channel Motion Control Encoder Feedback System

In order to quickly help users verify motor control algorithms without concern with underlying code-driven implementation with encoders, the paper designed a system for encoder feedback. We implemented common encoder protocols based on FPGA, and packaged them as modules in Simulink. At the same time, PCI Express communication is implemented to ensure data high-speed and real-time transmission. The users in Simulink can flexible configure and select the encoder protocol, acquisition frequency, acquisition channels and other parameters to meet different needs. This system has high flexibility and applicability, which can help the motion control system get feedback quickly.
