Defining the Final Angular Position of DC Motor shaft using a Trapezoidal Trajectory Profile

This paper presents the experimentation to define the final angular position of the Maxon RE 25 brushed DC Motor shaft, when using an implementation in closed-loop position control configuration is proposed of the Digital Precision Motion Controller LM629. Reporting the final angular position through a GUI implemented in LabVIEW. The Digital Controller LM629 generates a trapezoidal velocity trajectory profile, which by integration defines the reference angular position as a ramp for the final angular position of the Maxon RE 25 DC motor shaft. The experimentation and experimental results are described, showing high performance, high precision, and effective positioning time.
