Various options for electronic rebalancing loops of strapdown floated gyroscopes

A general view is presented of the different concepts for the problem of electronic rebalancing loops of strapdown floated gyroscopes. The loops of rebalancing analyzed are analogue, binary, ternary, and time modulated types. In particular, the errors are discussed along with the interfaces and the electronic implementation of each one of the loops. The rebalancing control loops are compared and one of them is selected for future analysis and simulation.
