Nanopositioning Controllers: Multiaxis Digital & Analog
| Digital servos provide advantages over analog circuits when high positioning linearity is important or when control parameters need to be modified frequently. This could be the case when load changes occur or when different motion profiles need to be optimized for minimum settling time or optimum tracking accuracy.
Analog servos are usually less expensive than digital servos. If designed well, they provide very low noise and fast response at a very attractive price.
All PI piezo nanopositioning controllers come with tunable notch filters and provide the highest closed-loop bandwidth in the industry.
