Hi,

I'm starting to learn control (state space approach) and have a question:

Most of the time the states (eg. position and velocity) can not be
measured directly, therefore we need a state observer. What if in the
case where the states are position and velocity, however, only the
acceleration can be measured? How can we use the measurement of
acceleration to help designing the state observer?

I am not sure if it's true that as long as we know the initial velocity, we can integrate the acceleration measured to give the velocity so that we only need a reduced-order observer (because velocity are known by integrating the measured acceleration).

Thanks for reading and advices.
