Hi
We have the position and velocity of products on the conveyor in time
t=t1. How can we estimate position in time t=t1+T (T is scan time) if
we know max.acceleration, max.jerk, max. velocity for this product?
Product is on the conveyor. We need probably Kalman filter, but can
somebody tell me formel how can we calculate position in t=t1+T.
Maxima don't help. What you need is current estimates of position,
velocity and maybe acceleration. If you have these, the estimated
position at t2 is x1 + v1*T + a1T^2. Then you also update the
estimates of x, v and a (and the state covariance estimate) by using
the Kalman filter equations.
