| Keywords: Third-order motion profile.svg In motion control a common need is to move a system from one steady position to another point-to-point motion Following the fastest possible motion within an allowed maximum value for speed acceleration and jerk will result in a third-order motion profile as illustrated in this image The motion profile consists of up to 7 segments defined by the following acceleration build-up with maximum positive jerk constant acceleration zero jerk acceleration ramp-down approaching the desired maximum velocity with maximum negative jerk constant speed zero jerk zero acceleration deceleration build-up approaching the desired deceleration with maximum negative jerk constant deceleration zero jerk deceleration ramp-down approaching the desired position at zero velocity with maximum positive jerk If the initial and final positions are sufficiently close together the maximum acceleration or maximum velocity may never be reached Based on raster 2009-10-13 ZooFari User ZooFari/Template SVG Velocity Acceleration Jerk mechanics Motion curves | ||||
