Thus force feedback and acceleration feedback are equivalent for solid bodies.

When there is a flexible payload, the two sensing options are not longer equivalent.

- For light payload (Figure [1](#figure--fig:preumont02-force-acc-fb-light)), the acceleration feedback gives larger damping on the higher mode.

- For heavy payload (Figure [2](#figure--fig:preumont02-force-acc-fb-heavy)), the acceleration feedback do not give alternating poles and zeros and thus for high control gains, the system becomes unstable
