Basics of motion-control profiles, Part 1: Context
How a motor ramps its angular position or rotational velocity from a starting point to the intended target value is a complicated topic which modern motor controllers address in many ways. Controlling the motion of a motor is a major design challenge since how a well a possible motor choice can ramp its speed and […]
