Dear All, Hope you guys can help on this. I would like to measure how stable is an object moving at a spped, let's call it the stability metric. For instance, an object is moving at a certain speed, but through the object history, we know that it changes its velocity with a certain amount, let's call it disturbance. The lower the disturbance, the higher the stability metric, which means more stable. And, I would like calculate stability metric which is a function of velocity and disturbance. Thanks.
