In order to quickly optimize speed loop control parameters, put forwards a kind of method to analyze the characteristics of the speed loop and regulate the control parameters. This method takes the Microsoft Visual C++6.0 for development environment, and uses LabWindows control as graphic display control design, The PC sends the time domain test signal or frequency domain test signal to the servo control system by port, and receives the response signal from the servo control system by the port. Then, analyze the static characteristic and dynamic characteristic of speed loop of servo system. Experiment result shows that the software has great on-line speed characteristics analysis functions, and it can provide a good data basis and monitoring functions for the research and development or on-line debugging of the servo system.In order to quickly optimize speed loop control parameters, put forwards a kind of method to analyze the characteristics of the speed loop and regulate the control parameters.
