Online Calculator for Time-Optimal Jerk-Limited Trajectories


Thread Starter


Dear control-forum,

I developed a generator for time-optimal trajectories with jerk limitation. You can calculate, display and download trajectories online.

The generation of jerk-limited trajectories is often used in automation and for the movement of large and precise machines (i.e. large telescopes), but also in robotics and CNC machines. Usually, a trajectory generator is placed in front of a control loop to generate a setpoint without discontinuities. Even though the topic of jerk-limited trajectories seems simple and there are hundreds of publications on the topic, most proposed solutions are either approximations (so the given motion constraints are either not exactly matched or not time-optimal), or only work for specific sets of parameters. What sets this trajectory generator apart is the possibility to provide a time-optimal solution for any given motion constraint. Another advantage is that arbitrary start and target motion states (hence position, velocity and acceleration) can be chosen.
The online version of the trajectory generator allows you to fill all of these parameters in and to display the trajectory als XLS or CSV.

I hope you find this a useful resource to quickly calculate jerk limited trajectories online. I am happy to listen to your feedback.
