Trajectory generation techniques such as 7-segment S-curve profiles, asymmetric acceleration and deceleration, continuous contouring, and electronic camming are standard features in modern machine design. They provide engineers the tools they need to make controlled loads move faster and more efficiently. This paper will take you through the mathematics of motion profiles, discuss which profiles work best for which applications, and provide insights into how modest changes in the profile parameter settings can create big improvements in throughput.
This article describes the advantages of open-loop sensors over closed-loop current sensors. Examples of LEM and Honeywell open-loop sensors are described.
